69 Gas Caps revisited - original Cap?

[Dave69x33]

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.

Thanks again.

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

Don't know if it's original, but here's a photo of mine

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.

KOOL! I had no idea.

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).

Manufacture's mark stamped into one of the ears.

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.

Stant part number 10646.  See attached.

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.
