I’ll look through my collection of gaskets. However, I read an old hot rod magazines article about base gaskets. They claimed the factory ones were too thick and people tended to tighten then down too much and warp the base. They cut some out of thinner material after they milled/replaced the warp base with better results. I’ve prob got some old ones but I use the thinner ones supplied in my Chicago carbs kits with no problem. I do remember the ones with REAR stamped on them. I think they were grey. I may have some. I doubt I’ve got any in oem packaging, though. I’ll look for you.

I have one here, but my calipers are not to be found.....

They are tan in color & textured.

I can mail it to you if you like Bob?

Be on the lookout for an FJ5 envelope.

Here’s what I found. Probably came from Bill Overcash stash I bought after he passed. About .070. It won’t let me post a picture from my iPhone

Thanks to Barry, the NOS one measures .034 thick

Thanks for measuring it, I scanned it before it left so I could add the thickness to a reference image.
