1988 gas cap correct thread color

[John G.]

Pictured are two "S" gas caps. The TIM&JG states that the threads are "large off white plastic threads". Which of these two colors is the closest to correct?

Does either one have the correct date of manufacture stamped at the bottom?

Yes - the off color one which also has a green insert. I'm going to a scrap yard probably tomorrow so if I need something different now is the time.

The one that's closest to correct is the one on the left. I believe the one on the right originally appeared just like it although with, perhaps, a slightly yellower coloration. The one on the right has been exposed to gasoline for a long time. That's what causes it to darken considerably.

Attached are photos of two 1995 Corvette Gas Caps displaying a date code. The first shows 171-4. This is June 20, 1994. This is one a 1995 Corvette that has a build date code of August 4, 1994. The second shows 079-5. This is March 20, 1995.
Hope this helps.

Unless I can find a better one I'm going with the yellowed one. It has a date code of 1228 and my car is a 5/88 manufacture.
