Title: Hurst Shifter date codes
Post by: JoeC on April 06, 2016, 08:10:12 PM
I was the one who said the 4 digit code was a Firebird shifter.
From what I have seen , the 4 digit code was used on the early OEM Hurst shifters 1964 to 1968/69
All the  1969 Camaro shifters I have seen have the 6 or 7 digit code but it could be that some 4 digit coded shifters were used on Camaros.

I didn't keep track of the 4 digit codes but have a bunch or codes from actual 1969 Camaros .
here are some including the earliest one I have and the latest one I have and some in-between.
The earliest one I can find is Oct 1968 so I don't know when they changed to the  6 or 7 digit code.
Would need more data to find the latest 4 digit code and earliest  6 or 7 digit code

Joe I cut your post above from that other thread and started this topic.

You may be onto something. I will check to see what else I have for Pontiac Hurst shifters later this evening. A quick look at a 68 GTO shifter shows the similar 4 digit code (but coded for Feb 68) as that Firebird shifter.

OK I checked. The two images below are not from Camaros, but are related to the date coding.

68 GTO Hurst 4 speed shifter dated Feb 68 and 66 Lemans Hurst 3 speed shifter dated September 65.

In addition to the 68B2 I posted a pic of in the other post...I also have a 19D33D & 39D21(Q or O?)

Do you have dates of the cars those shifters are from?

Your other shifter dated 6 8B2 was in your 12B car.

The one posted a bit earlier was 6 8B2 from a 10B car.

I remember both cars the shifters came out of, but back then we never looked at dates. So, sorry I cannot provide much.
Added pics. last pic 68B2 is off 12B Nor. X22

Thanks for starting this thread. I was just about to. :)

If 69 owners could post their shifter dates and also their car's build date, we'll tabulate and see what the data says....

I think I've done this before when we were discussing shifter dates, but here it is again:

69Z28-RS     09C (18Sept1969)      Shifter mfg code      890731C    (Aug'69? mfg 31Jul?)
Title: Re: Hurst Shifter date codes
Post by: bcmiller on April 07, 2016, 01:28:17 AM
Gary, Joe may have a better idea. I know I have checked around in the past to try to find answers.

All I am PRETTY SURE of is the month and year. I THINK the numbers and letters after that are the batch code - but I don't know the exact decode for that part. Or if there even is a decode for the batch number.

Thus the reason for this thread and requesting data.
Title: Re: Hurst Shifter date codes
Post by: 69Z28-RS on April 07, 2016, 01:44:12 AM
Could be...  the 0731 was so close to the Aug 69...  I thought it *might* be?  ie. maybe a daily batch?
Note:  PaceMe (Steve Shauger) has a good understanding of these codes, as it was info from him that provided the info on month/yr/etc...

Here's another one.  This was a swap meet shifter I picked up long ago, and traded to Dave Hawksley (maybe he's cleaned it and has a better photo of the mfg code)... :)

Looks to me like:    590423D

Title: Re: Hurst Shifter date codes
Post by: bcmiller on April 07, 2016, 01:53:42 AM
Not likely a date since you note in the first post several with numbers in the batch code above 31 (max number of days in any month).

The month/year code info is pretty widely known.

I got this shifter from Gary (69Z28-RS). It came from a Camaro, but I can't confirm the build dates of the car.

190423D (Jan 69)

(http://i1164.photobucket.com/albums/q573/SgtHawkUSMC/69%20Camaro%20SS396%20L34/69%20Trans%20M21%20Muncie/69%20Shifter/IMAG0688.jpg) (http://s1164.photobucket.com/user/SgtHawkUSMC/media/69%20Camaro%20SS396%20L34/69%20Trans%20M21%20Muncie/69%20Shifter/IMAG0688.jpg.html)
Title: Re: Hurst Shifter date codes
Post by: JoeC on April 07, 2016, 11:45:00 PM
I have 3 shifters at home I forgot to ad to my notes
78D2
19D53D (same number as one in my notes but different shifter)
690511C

I thought the 78D2 was a Firebird shifter but now that I think about it, a July shifter seems late for a 1968 car build

Hard to say what Hurst was doing with the codes/numbers
with the 6-7 digit codes, some have one letter some have two
a lot of "Ds" seem to show up

I know that approximately in the early 70s  , Hurst changed the numbers used on the aftermarket shifters.
They went from using a serial number to using an ID code such as 391- 4340

suturb110 - thanks for your data.  Would you happen to have a pic of the date code?

I think we are starting to see a pattern that some early 69s used the 4 digit date code.  Now hopefully more data will give us the approximate time of the change.

Hi,

Attached is a picture of my early 1969 Z28 shifter. Build  code 09D 1968 Van Nuys.  The shifter date code is 8 8 D3. The first "8" was stamped real lightly by the bolt.  The rest of the date code is real clear. After I resized the picture the first "8" got more faint.

Thanks,
Mike

We haven't been keeping up with it, but are all these '69 Shifter bodies marked '3138', whether early or later ??  Or did they change the model number along with the mfg code  in the September '68 timeframe??
Title: Re: Hurst Shifter date codes

Post by: JoeC on April 15, 2016, 04:52:45 PM
3138 is the Hurst part number just for that stamped part that makes up the outside case

It was used on many OEM shifters (Camaro Firebird GTO and others)

Post by: X33RS on May 10, 2016, 02:30:37 PM
Mine is super close, a 12D car with a 12-68 shifter.  I don't think there is a week given on the shifter code so can't narrow it down further, but my car and shifter are both in the same month of the year so they can't be more than a couple weeks apart.

However, a shifter, or most any other date code spread 2-3 months apart wouldn't worry me much, as long as it's obviously before the car build date.

Post by: GreenNV on November 04, 2016, 03:07:12 PM
Here's a little food for thought on the coding witnessed on the shifter bodies.

First let me preface this by telling you that a very good friend of mine has taken dozens (if not hundreds) of shifters out of cars when rebuilding Muncie 4-speeds & Hurst shifter bodies at a specialty restoration shop over the past 30+ years. Two people there had often taken note of the codes on the cases and referred to different prefix numbers as being associated to GM, Pontiac, Olds, etc. (i.e. 1=Chevrolet, 2=Pontiac, 3=Olds and so on so forth). It was also said that the second character likely determined the year, and the third related the month. Apparently the coding was done differently in different years where alpha letters were used for the months of one year while numeric values were used in others.

In recent conversation with Peter Serio, the two of us discussed the coding and batch numbers witnessed on different cases and he is certain that different coding was batched for each motor division and that the prefix is likely the plant code ordering the shifter rather than the month which is what many people are thinking the first character was? For those of you who do not know Pete, he like my friend has been active in the restoration field for many decades. He is widely known for his Hurst Shifter restorations within GTO, Firebird, Camaro circles and has restored hundreds and hundreds of different Hurst shifters. Pete is touted as being one of the best and has restored hundreds of them.

Peter Serio
2719 Columbus Ave.
Columbus, OH 43209.
614-258-3500

He's also written books on shifters. http://precisionpontiac.net/Book_Volume1.aspx

Pete understands many of the differences seen in a shifter body that many people truly don't? In a lengthy discussion, he informed me of many changes seen in the shifter bodies between one motor brand and another, and also educated me on the subtle changes made within a shifter body when GM would send change orders to Hurst facilitating things like reverse lockouts etc. When the new columns came out with locked steering in 69, there were problems where people inadvertently locked transmissions up by getting the shifter to engage reverse and forward gears at the same time. This created many issues and potential lawsuits for GM where changes orders resulted in multiple manufacturing changes within the 69 shifter bodies to correct these issues. He went on the tell me that one cannot always take two 69 Camaro shifter bodies apart and attempt to interchange parts because there were various part changes within most years especially in 69. I told him about the date sequence referred to in this page and he strongly suggested it may not be as many people think?

I know another person in the hobby that takes one look at a shifter body and you can ask him, hey what's that from? He'll quickly answer that's easy, 29D coupled with that particular offset is 69 Poncho out of a Firebird while he can look at another body and spit out out 1967 Big Fat Chev. I have spoken to many people heavily involved in this hobby that know Muncies and Shifters intimately and while most have different opinions on dating/coding, the one thing that has been commonly discussed is how most concur that the first character (at least in some years) is related to the motor division.

Just sharing some of what I have learned from a few who are way smarter than I  ;D

Green NV & Mr Serio, appreciate your insight and experience that gives food for thought. All the dates provided above are supposed to be out of cars that the owners are stating the shifter is the one "born with" their respective car. I have the 12B Nor 68B2 Hurst. By your observation, this is not even a Chevy (1) shifter. So, what is my shifter out of? What would GM division 6 be? Why would it be in my Chevy? And work, fitting the application?

GreenNV,

You are pretty new here. Did you ever introduce yourself and tell us your background? New insight is always welcome here, just don't try to set the world on fire. Eh?

Your observations are interesting, but don't seem to fit what we have observed in original cars.

Same coding for my Shifter. The original from a 10B Oct 68 Z, an early car. Reverse lockout does and has always worked flawlessly. I don't see how the shifter could engage 1st and reverse at the same time, but if that could happen, it would be related to the internal rails of the shifter itself, and would be a design flaw unrelated to reverse lockout..

Looking at the shifters listed in this thread is only but a small sampling of codes out there and pertains to a couple years and perhaps one model only. While you can conceivably think it could be month, year for maybe 68/69, what about all the other years and codes from all the other motor companies where the coding is very different and 8 characters long? Kinda begs you to ask the question doesn't it? That's why I asked Pete, and he doesn't think it's date coding, but actually batch codes.

Example...what are all these zeros about? Month zero then year??? There's gotta be more to this.

I'll answer your questions when you answer mine. And when you say this is a sampling of a couple of years and perhaps one model only, that is an insightful observation as this is a 1st Gen site and Hurst usage of one model year. So, yes, that is all I am concerned with and all this site is and should be concerned with. Let other makes/models make their own conclusions. You surely cannot deny the facts of the sampling and you are up against some of the best minds in the hobby. We, collectively, are open minded to divergent viewpoints, and do not have our head in the sand. What you propose is not consistent with the evidence. Do you see a pattern from the data that suggests different?

I believe everyone could be right.  It does seem odd to me how some shifters do have extra characters while others don't.   And as far as I know there hasn't been a complete breakdown or understanding posted on the site anywhere that I've seen. I don't think it's all completely understood yet.   Just looking at the list, mine is the only original shifter on that list with 8 characters. 

I tend not to believe the first digit is a model number, nor is the second digit a year in my case.  Looking at mine for instance you have to look at the first 3 digits.  It's the only shifter in the list that belongs to a December built car.  Therefore the only explanation that makes sense to me at this point is looking at both the 1st and 2nd digit together.  That looks like a month to me (December)   The 3rd digit on mine would be the year (1968)
   I have no idea what the "O" is and a pair of D's don't make much sense to me either.   But I could make a good guess at the 31 as possibly being the day of the month since my car was built around the last week of December.   That's just a guess but it makes the most sense to me at this point.

I agree with X33 ... as I've stated before.   The Hurst code is not ONLY a date code; it makes more sense that it's a Hurst batch code, BUT it does have a 'date' encoded into it (I don't think there's any doubt about that, at least for the Chevy shifters for '69, where we have TOO many examples to ignore.  Th fact of a date included batch code makes sense given the warranty issues that would be faced when Chevy sent back to Hurst a malfunctioning Shifter from a 'warranted' car for repair/replacement.  Hurst would have a means to determine from only the shifter 'when' it was made and how long any warranty Hurst supplied to Chevy would last.

Not only that, but those stamped numbers would had to have had successive coding for versions of the same shifter series. Pete Serio told me of at least 3-4 changes in the 69 model year alone due to all the change orders GM sent to Hurst regarding the column lock and the changes that brought throughout the year. I would bet one of those characters in the stamp is the series for revisions. I'd guess it was the first because of the 1/2/3 but then why the 6 or 8's later in the year? Or are there actually other prefixes such as 4/5/6/7 that we simply haven't seen yet.

Here's one from another 69 that starts with a 3.

(http://www.yenko.net/ubbthreads/pics/usergals/2016/10/full-1402-51205-pa290014.jpg)

So much is still unknown about shifter coding, dates and batch codes or series? It's fantastic to have CRG and its members compiling data such as this, but there's a lot more remaining to be learned before attempting to pull an actual date from this code, or how it can actually be deciphered.

GreenNV:   The one you show fits perfectly with the encoding we've determined (from original '69 cars/shifters).   The first (one or two digits) is the MONTH, the 2nd (or third) digit is the YEAR.   The one you show is for March of 1969...  the following characters/digits are perfectly able to account for 'versions' or 'batches' that seemingly only Hurst knows about at this point in time.. :)

Generally, at this point, we are looking at codes from 69 Camaro Hurst shifters. I am pretty sure coding changed for 70 and later. Let's try to not muddy the water too much. Let's stick with original Hurst shifters from original 69 Camaros.
Title: Re: Hurst Shifter date codes
Post by: X33RS on November 05, 2016, 09:08:25 PM
I think you're right Gary.  If you look at the first 3 codes on mine (128)  December 1968 is the only thing that makes sense.  So I believe looking at the shifter posted just above, I agree that would likely be a March 1969 shifter.

Bryon, I have another factory Camaro Hurst that has an original 70 Camaro stick in it.  I believe that shifter body is dated very late in the 69 calendar year.  Might have a slightly different sequence of numbers if I remember right.  I'll leave that out of the conversation for now.  But if it becomes crucial to determining any information on numbers/letters and how they might of changed, I'll dig it back out.
Title: Re: Hurst Shifter date codes
Post by: bcmiller on November 05, 2016, 09:52:15 PM
You can dig it out and post if you want. At the beginning I had posted a couple of Pontiac shifter codes.

Other GM divisions were using Hurst shifters several years before Chevrolet.

I just don't want us to lose focus. No we don't understand everything, but I feel we are on the right track with the date codes used for 69 Camaro Hurst shifters.

Agreed. Why there other formats in non-69 Camaro shifters is not part of this discussion. Showing some examples from other known original shifters is fine, e.g. here is a 68 F-bird 03C shifter.

something I noticed over the years working on Hurst shifters

they changed from sliver cadmium plate to black phosphate about 1970 from what I can tell

the aftermarket shifters also changed from sliver cadmium plate to black phosphate

I think HURST worked in the change over a period of time because they had so many different shifters

Another 69 shifter. This is a restored one I picked up for my 69 build and will be going into my 05A car. I'll need to find some original bolts for this one before mounting it up.

If possible, I would like to see any additional posts be from original cars with original shifters.

You can delete that post then.

It's one number off the original from my car and thought the more you can learn about dates the better, but I guess this thread is only for original "born with" shifters for the 69 model year only then?

Post by: bcmiller on December 10, 2016, 02:16:26 AM
Well since this is a First Generation Camaro website, and the only Hurst shifters that we are doing research on are from 69 Camaros, yes. That's what we have determined in this thread that we are concentrating on, and we are trying to figure out the stamping codes. Unknown shifters don't help much.

My earlier post was a REQUEST, not a demand.

Thanks.
