Sometimes you don't get a good stamping because of the roughness of the block surface.
332  Camaro Research Group Discussion / Decoding/Numbers / Re: Strange VIN on orphan 69 L78 (?) on: July 26, 2009, 09:21:41 PM
Looks like it could be OK.

Can you make it all out?  Is is something like 19L555192?

What is the date code on the front pad?

This is a 4 bolt main block with the large oil galley holes, right?

Date code of P8C05c is too early for the C to indicate an M22.

I have been trying to research the small c at the end of the date code on 1968 Muncies.
Have not been able to find much out yet.  Looking for someone that worked at the
plant at that time to ask some questions about the date stamping.

Buddy,

Thanks for the pictures.  Looks like I did it almost right.  I stopped at the center of the weather strip channel.  I had the weather strip out.  Looks like I should have painted it more. I will have to fix that.

What ever happened to that car?  Hopefully it is still around.   
335  Camaro Research Group Discussion / Restoration / Re: black on tailpan on ss cars on: July 25, 2009, 07:40:55 PM
I just repainted the tail panel on my car satin black (along with the hood - did the hood to have a look different than everybody else).  I am glad I used satin.  I did it that way because all of the SS cars that I remember were satin.

One question though.  Are there any diagrams as to where the black stopped?  I stopped about the center of the bumper (had the bumper off) on the bottom, but was not sure in the trunk area.  I went at about a 45 degree angle toward the trunk opening at the corners and stopped in the weather strip channel.

Is there a casting date anywhere on the center housing? 
337  Camaro Research Group Discussion / Originality / Re: correct shifter for 1969 on: July 23, 2009, 08:48:45 AM
The 3138 shifter body was used for several OEM applications.

I took a look at that add.  I think I would give them a call and ask the questions.  It does look
like it has the correct style handle (bayonet style handle - not bolt on). 

They might have listed the wrong number in the add (they have 3128 and original was 3138)
or maybe that is just the number they are using now.   Sorry, I don't have more answers.

I think they need to do some more cleaning and use a wire brush.  I don't see that code in
any of the documentation that I have collected. The format of the stamped code should look like

CB G 112 1 E
(CB = Ratio, G = Plant, 112 = 112th day of year, 1 = shift, E = Positraction Source)

Rich,

Check this link and scroll down to the transmission section.
http://www.camaros.org/trans.shtml#4speed

I believe the OEM shifter body is 3138 and it used a 5325 round handle.

I believe 391 7438 is the number of the current aftermarkt Hurst Competition Plus for a 69 Camaro.
This is the number for use with and without a console.

What ever happened?  What is the guy's name or did he decide to give you your money back?
341  Camaro Research Group Discussion / Decoding/Numbers / Re: 1968 Muncies - date code with small "c" at the end ? on: July 20, 2009, 09:11:06 AM
I read through the gang stamp information.  I don't know if that was going on with the date stamps though. 

I did check the M21 in my car and it DOES have that small c or whatever character at the end.  I believe it is a
replacment transmission though.  Date code is after my build date by 5 months and so far I can't find a partial
VIN but it is probably on the top of the transmission.   
342  Camaro Research Group Discussion / Decoding/Numbers / Re: 1968 Muncies - date code with small "c" at the end ? on: July 18, 2009, 08:41:34 AM
The gang stamp could help explain something.  I don't know.  It sure is not a true full size C because I have a picture of one with a March date code and it uses the full size letter.

It must signify something.  How about small c for "close" ratio - in other words NOT an M20. 

Did anyone try to cross check that?
343  Camaro Research Group Discussion / Decoding/Numbers / Re: 1968 Muncies - date code with small "c" at the end ? on: July 16, 2009, 07:02:06 PM
Does anyone know anyone that may have worked at the Muncie plant in the early part of 1968?

344  Camaro Research Group Discussion / Decoding/Numbers / Re: 1968 Muncies - date code with small "c" at the end ? on: July 16, 2009, 05:00:23 PM
OK.  Thanks.  But that thread is over 2 years old.  Has anyone figured out any more since then?

Inspection mark is usually on the top of the transmission.

The small c definitely does not stand for Chevrolet since I have them on Pontiac and an Olds transmissions.

The initials mentioned on the side of the case in that old thread were probably scratched into the mold
by the person doing the casting.  Probably that persons initials.  I have one with MH on it.
345  Camaro Research Group Discussion / Decoding/Numbers / 1968 Muncies - date code with small "c" at the end ? on: July 15, 2009, 11:44:12 PM
OK, I know the codes for M20, M21, M22 (A, B, C) were not supposed to start until around late October 1968, at least on Chevy cars. But could Pontiac and Olds have started sooner?

I have a Muncie that I think is from an early 1968 Firebird.  The date code is P8B07c with a partial VIN of 28L100919.  I found pictures of two other transmissions with a similar small "c" stamp after the date code.  All stampings look very simillar.  I wonder if someone is trying to fool people that these are M22s or what is going on?  These are all from different parts of the US.  The trans I have was in an IMCA modified stock car, converted to a 2 speed with M20 gears in it.  So it was not fooling anyone there. I have gears to put it back to being a 4 speed M20.  I have never seen any of these small "c" marks on a Chevy transmission.  Does anybody have any ideas?

I have attached a picture.  This is from Muncie #2.  I have pictures of the two others but can't post now due to size limits.  I can send them to anyone interested that would like to comment.

Muncie 1 - the trans I have - date code P8B07c with a partial VIN of 28L100919
Muncie 2 - an Olds 442 trans? - date code P8C06c with partial VIN of 38Z117242
Muncie 3 - a Pontiac trans (GTO ?) - date code is P8A19c with partial VIN of 28P244597

Any help you can provide to explain this will be appreciated.
