Background: I'm the 2nd owner, have had the car for over 20 years, it had 67k on it when I bought it, so I believe this is likely the first time the Autolite 4100 has been off the car. But if this is not an original factory 4100 gasket that would be interesting to know. I took lots of good pics before removing it and prior to disassembly if any one needs pics of an original 65GT San Jose built car.


 So the carburetor base gasket and spacer gasket look like this?
 They have a metallic core throughout and the exposed metal areas seen in the pic. It is metal, tested it with a magnet. Nothing like what you can get in the parts stores now.

Can't recall ever seeing one of those on an original car.

Center section appears open (no gasket)  and tabs made in the gasket on this side don't appear to be like others I've seen - including the material is produced from

No markings on the surface?

It doesn't look like any of the original gaskets that I've removed.

I've seen that style originally installed before.  Don't recall assembly plant/date though.  It was a reddish material, metal reinforced.

Those aren't tabs on the sides, just the grease buildup from the foot print of the carb.

Are the originals usually closed in the middle, 4 separate holes?

I acquired a new car take-off intake/carb setup 5+ years ago and it had the same gasket as in your pics.  The bottom gasket had black paint around the edges, so I'm pretty sure it was original.  As you can see, the inside is open also, both gaskets were the same.

So 65 application we can see.

Will be on the look out for later and more of these - thanks for sharing

This is the only marking I found, VG.  Maybe for Victor Gasket?
Also interesting date marking on the bottom of the carb.

The spacer date code will be kind of generic to a broad range of cars, don't expect it to be close to when your car was made.  Seems it's like carb body date codes, only changed when there was a revision, not modified through production runs.
