69 Gas Caps revisited - original Cap?
« on: February 23, 2008, 08:32:56 PM »
Back in October 2006, there was a discussion on 69 Gas Caps.  I dug up my original cap, or the cap that was on my 69.  I can not be sure if it is “the original” cap but it appeared to be.

In the picture “Gas Caps_1” shown below, the cap on the left is the replacement or reproduction.  It was 10 years ago I purchased the cap and I can’t remember if it was a repro or a GM replacement.  The cap on the right is my original.  Picture “Gas Caps _4” shows the “Vented” and “Anti Surge” scrip stamped into the cap. 

Notice the difference in the location of the ears on the OD versus the orientation of the handle tabs. The pic #2 shows the different plating on the inner detail.  Again, the original cap is on the right.  Pic #6 is the “S” stamping on the tab on the repro/replacement, and pic #7 is the “S” stamp on the original cap tab.

Does anyone have an original or survivor 69 with “the original” cap?  I would like to see pictures of it and know the plant and build date of your Camaro.  My 69Z is a Norwood car built 05A, or during the 1st week of May.

Thanks!

Here are pictures #6 and #7 showing the "S" stamps.  Pacecarjeff mentioned in the first discussion that the original caps had an "SM" stamped on the tab, and replacements had an "S" stamp.  Are gas caps with "SM" stamped on the tabs the caps that were on the 69 Camaros when they left the factory, and were the "S" stamp tabs GM replacement caps?

JohnZ....is your cap the original?  What is your stamping?

Thanks again.

Mine isn't the original - previous owner replaced it.

Amazed it has come to this these days. I believe that my cap is original to my Oct 68 build 69 Z. When I have a chance, I will get some pics of mine. I do know it looks like those in the pics shown, and I have had the car since 1982, so I'm pretty confident it's the original one. I'll  get back on it.

The biggest clue is that the original 1969 caps - do not have "ears"

The cap Tom shows above IS an original 1969 cap.

Thanks everyone.  Let's keep digging thru our junk piles to look for original caps, oil dip sticks (topic from another post), etc.  Perhaps, others with survivor cars will post pic's of their caps (and please remember include your VIN # and/or build date and assembly plant location of your 69 Camaro).

As this summer's show season kicks in, I'll be on the hunt for survivor 69's.  I keep a list of things to look at and photo document, then share with you throughout this year.

Cap from my 01C Norwood '69 RS (VIN #19N581767; final assembly on or about 20-21 Jan 1969) is shown in this and the next post.  My cap is the same as the one in the first posting in this thread from Dave69x33.

As far as I know it is original to my car.  Still had some of the dealer undercoating overspray on it.   I had to clean off some of the overspray in order to get a decent pic. Undercoating covers the bottom of my gas tank and some of the filler neck with overspray on the cap. 

First pic here.  Secon pic in next post. 

It is marked with the stamped words "VENTED" and "ANTI SURGE".  There is also a stamped "S" in the center of the cap and a manufacturer's mark stamped on one of the ears (pic in next post).

Thanks Rich69rs.  It’s interesting to see an "SM" stamped cap.  My 69 is a 05A car, VIN 9N638712.  Again, I can't confirm it the original cap but hopefully we will see more pic's of original caps to see a common trend with round caps or caps with the small ears.

Dave,

I just noticed in the pic of your caps, the pic that Tom posted, as well as pic of my cap, all appear to have the same "S" stamped in the center.  Wonder if the "S" is possibly an application code; "for a car where the gas tank is vented through the gas cap"?

Not all gas caps of GM cars from the 60's were vented.  The gas cap on my '66 Chevelle clearly states that it is not vented.  On the Chevelle (and other GM A bodies) the gas tank is vented through a separate line from the top of the tank, up into the trunk, where in makes a 180 degree bend and the back through the trunk floor.

That same S is on the caps you can buy right now at Walmart.
It was for Stant - the suppliier to GM.

Mine also has a marking on the on the tab but it does not show well in the first photo. mine appears to read "GM" inside two circles. Here is a fresh photo of the logo.

Tom -

Do you think yours could be stamped "SM" as in Richard's photo above?  SM = Stant Manufacturing.     :)

Paul,

Not positive, but it looks like "GM" to me. It also appears to have two circles stamped around it instead of one like in the "SM" stamp shown on Richards cap. There is not enough to be positive what was stamped. The rivet does have the large "S" like the other caps.

That's actually "SM", with the horizontal line missing. The "S" on the center rivet was on all Stant caps, and the "SM" logo is for Stant Manufacturing.

This video has a good shot of the gas cap. Ironically look 3:02 (but it is not a Z28) minutes into the video on the CRG youtube channel. It appears to have raised letters, ears and shows the handle perpendicular to the line in the cap. https://www.youtube.com/watch?v=Bjq-KbGlKwM

I watched that video a while back, and did not believe what I saw, and that was the cap with ears.
 I have restored a bunch of the round caps over the years and looked at quit a few original cars with there born with assy line gas caps including 1970 Chevelle's that used the same "Round" Stant vented anti-surge cap.
 I would have argued long and hard that the ear cap had not even been made in 1969.
Any thoughts on the one in the video ? Maybe a early engineering test thing ?
 Shauger have you seen the video with the ear cap ? Interesting, never say never ?

Here's what I believe to be my original gas cap. On the one tab is "SM" surrounded by 2 circles. The "S" is kind of funny shaped in that it has a straight line between the 2 arcs of the "S" I've included pic, but it's very hard to see.

I would also have argued that there were no gas cap ears in 1969.   
And this is not a case of different vendors - these were all made by Stant.

All the yard cars that I was 100% sure were original and had been crashed back in the day had the no ears cap. 
But who really knows for sure? 

Hey that sure makes it easy, that one looks just like the cap they are selling at walmart today....   LOL  ::)

Its time to stop discriminating against those of us with ears. I spent all day cleaning mine in evaporust. Pics of mine with ears and SM stamp. Maybe ears with SM stamp are super rare!

Maybe we should start another poll - here's my 2 from the Z11 and the X77 - notice the clocking of the ears as compared to the previous pics.

I know, they need to be soaked for a week or two in Evaporust -

Starting to look and sound like the old "early vs. late" design deal. Wonder if we can get close to a time period when it changed - if enough people respond, we can probably get there.

My 2 - 01C X77, 03D Z11. I need to go get a pic of the 12A L78 car to go with them.

Yes, it looks like it's time for another survey...

My gas cap, which I believe to be original to my car (and is still on the car) is round, no ears, S stamp in the center, SM stamp on the bracket.

Too small of a sample size to pronounce anything yet. Hard to tell if some of these are original to the cars, too -

I can speak for the X77 from March of '73, the Z11 only from '94.

I guess we need a lot of respondents -

My 03B NOR has no ears

Interesting.. So why would Stant produce two different style caps during the same period of time ?
It's not an early vs late thing either since we are seeing both styles throughout the year.

Since the caps aren't dated (as far as I know), there's no sure way to determine whether they are original to the car, or were replaced at some point. In 1969, and certainly into the early '70's, most gas stations pumped the gas for you (I worked for both Mobil and Union 76 while in school, pumped many a gallon), so leaving the cap tucked between the filler/plate door and letting people drive off was a rare occurence. How many caps do you see on the side of the roads nowadays ? Plenty. How many caps failed emissions testing and had to be replaced ? None - we didn't test then. Point being - I don't think I have ever replaced an early gas cap, dating back to my Corvair and Bel Air days. If most caps are originals, and survivors have the same spread of caps, it's going to be a difficult question to answer.

Just my two $.01's - but keep the discussion going. Somebody has to have a clue. Survivor owners ?

Just to add a data point my 9B of 68 survivor had the eared type cap as shown. I had never seen another one until this thread. I can't confirm it wasn't replaced however it had plenty of patina.

Besides the 3 cars I have had for a long while, I also had a parts car + a tank bought from a friend that appeared original in all respects. I think 4 of the 5 caps had ears, which I dismissed as replacements, understandably. I always thought it odd that so many original caps where lost or replaced. Since I could not say with certainty that the caps were original, I never replied with any information on thisdata. It would be nice to put this one to bed, especially since I have 4 caps that are believed wrong up till now.
My only non-ear cap. Several of the early posts show caps with recessed lettering opposed to the raised lettering on the non-ear & car pic with filler door.

I'm really leaning in the direction of a two-design supplier for the entire year. Here's a thought - did Stant supply this same cap to Ford or Chrysler in the same time period ? I don't frequent either manufacturer's fan club sites, but I think it's a related question. External caps are ruled out (like the '67-8's), but there are other models that might share the cap for '69 and later. Just wondering - possible substitution if the spec cap for '69 Camaros ran low ? Too bad we can't look at the part specifications like the CBTN major parts books.

'69 Van Nuy's Z.  04B.   Ears with what appears to be GM or SM stamp.  No idea if it's original.

I can vouch for my cap from 1982. I recently had to replace it with a new one, because fuel was spilling out the back when accelerating. A gentleman behind me let me know. So it was old enough for seal failure. Other than having been lost, I so no reason why it had ever been replaced. But I can't be certain.

My 06A Z28 has no Ears and paper sealing gasket, owned since 1974, have no reason to doubt its original to car.

Just restored a 02D Van Nuys Z28 and it had no ears and paper gasket too.

I have noticed before that the ear type caps have rubber gaskets?

My 12B VN Z28 has the cap with the ears and I've owned it since 76. I always thought it was original.

Interesting to see what some will pay for things. I kept an eye on this one just to see how high it would reach (which turned out to be a lot more than I would have paid anyway).

Then again, all mine have ears. I can't recall seeing an original eared cap lately on eBay - repros for sure in some cases. I'll keep looking -

I watched the same auction. I wonder how many "watches" are just people like us being curious?

I saw this with ears, ended much more reasonably. I don't like how its plated, and the stampings are different than mine. It claims NOS as a G-46, but I don't see a box. I assumed it was a replacement cap, but who knows?

The seller here (john Meissenger?) .. always has lots of NOS/new automotive parts... apparently he scours the dealerships for this 'old shelf parts'... I've bought things from him in the past, although I can't recall specifically what.. (not for my Camaro but a corvette, or el camino..)..   $103 seems a lot for a gas cap, but it is exactly like the one on my '69...  I went down and took a couple photos after all this 'gas cap talk'.. :)

There may yet be an early/late correlation to this subject, although the current data group is still way too small to tell. 

I gathered the little bit of the data that was shared in this post and entered it into a spreadsheet then saved it as a jpg..  Some of the info is missing or I wasn't clear about it, and those items are highlighted in yellow.

If you throw out my car (10A '68), and if the 11C and 12B cars are from '68 (I wasn't sure), then maybe there is an early eared version versus a late round version.

More info would definitely be helpful.  It would be great if those who already posted could provide the missing pieces or identify any mistakes I made.

Hopefully my chart attachment experiment works... if not, perhaps someone could coach me on a good way to do it.  It's worth a try....

Both of mine are Norwoods. I have yet to brave the barn to see what the 12A '68 Norwood L78 has on it, but I will add as soon as I can get to it. 01C car is an X77, 03D is the Z11.

Spreadsheet looks good, probably better if you keep control of it. Remarking files gets a little haphazard around here in previous threads - can be disastrous !

OK , my 06A Z28 is Norwood. Round with paper gasket as previously posted.

Guy I work for has quite a collection of cars, I Looked at his 1969 09A L89 Camaro Norwood car, today and it is round, paper gasket, it looks refinished, cant say if it is original or not. He also has a 20 K survivor 02D 1970 Z28, Van Nuys car and it has round with paper gasket, cap is identical to 69, same lettering and logo. He also has a 70 Ram Air 4 TA , 18 K survivor it is the same, both caps have patina and look original IMO. I have pictures of ALL caps, but having touble posting them. I also have a NOS round eared cap like in the ebay auction.

Hope this helps.

Just so I get it right, do you mean it is a 12B 1969 Camaro body built in calendar year 1969 (versus 1968)?

I have restored dozens of the round caps, and some that I purchased have had a rubber gasket. 100% sure these were later service replacements. Also on the round caps there are at least 3 differant designs of the back gold plated poppet housings. Some of the later design  poppet housings on the rear have 3 inverted dimples near the vent hole, this is because the poppet in side of these are made from solid brass and the dimples allow for a air path. The previous design used a stamped steel poppet with two partial relief holes on there edge to allow for air to enter or escape.

Later production Stant cap. Pretty darn close to my eared (original?) caps, but the logo change on the tab is a giveaway. I bought this for my 12A L78, as it has a non-Stant replacement cap on it (evidently for decades by the look of it, car was purchased in '95 and cap has not been touched since that time).

Regards,
Steve

P.S. Rubber gasket, as are both of my eared originals, 01C and 03D.

Updated the list with a few more bits of info.

Also corrected my car data on the chart...  Went to the attic to look at my original gas tanks and discovered I accidentally took the round gas cap off my 02B and put it on my 10A car.  Old tanks all look the same in a dark attic.

At first I thought my gas cap with the ears was the original for my 07A X77 car. I remember reading where it was not correct and so I purchased a round one. I'll first show pictures of the one that was on my car originally. You think this one could be the original after all?  Thanks!

'69 Van Nuy's Z.  04B.   Ears with what appears to be GM or SM stamp.  No idea if it's original.

To add to the database table - mine has the Rubber Seal with ears.   I'll post pictures this evening.

OK Gang, here’s an observation that I haven’t seen mentioned in these gas cap discussions yet (or maybe I just missed this detail).

My ’69 Camaro AIM (UPC 8 – page B6) shows gas cap part number 3843698.  In the notes is states “10-10-68, WAS 3914863 CAP ASSY”.  With a fair amount of googling research, I see an overall consistent pattern for these numbers (but not with 100% accuracy), as follows:

3843698 / typically ROUND cap / RAISED LETTERS / ANTI-SURGE on top and VENTED on the bottom.

3914863 / typically EARED cap / RECESSED LETTERS / VENTED on top and ANTI-SURGE on the bottom (discontinued from parts books 7-71).

So the question is, was the EARED cap the first production line version, and then replaced with the ROUND version sometime after the revision noted in the AIM?  If so, then is it possibly: EARS for early cars, ROUND for later built cars, and a mixture for the in between models while they used up various inventories? 

If we could validate that theory, and narrow down the time frames, I’m guessing we could have a lot of gas cap trading opportunities on hand….

Good observation.. and that info certainly should help resolve this...   but I'm a bit confused about the fact that the 'eared pn' was in the parts book until 1971.  If it was 'used' up early in the '69 model year, why wasn't it removed from the parts book sooner than 1971?  OR did it get preserved as a part number but with a rubber gasket in it??

AC GT53  thisis the original gas cap from the Lemans BLue 10D early Norwood car, there is a PN change, the early part number crosses to the AC GT 53.
