Assuming that it has the correct embossed lettering, it sounds about right except for one thing: I don't ever recall seeing one of these with a cork gasket. All that I have seen have a black rubber gasket. I don't recall seeing it described as cork in the JG, either.

I think 1972 gas caps are supposed to be gold dichromate, but I will have to defir to those who judge exterior more than I do. And yes, I know the TIM&JG does not say that.

Examples of the GM #3994339, the L71-74 gas cap that I've seen have definitely all had the "gold" dichromate finish. However, I'm less sure that very early examples of the 3994339 had this finish. If someone comes up with an apparently original 3994339 that doesn't have or appear to ever have had a dichromate finish, then I would say early examples of the 3994339 probably didn't have said finish. Certainly, later examples of the cap, still available to this day, have the dihromate finish.

I don't think this cap was ever available in the aftermarket. If, by chance, it was, I would expect that the same Stant-manufactured cap was what was available.

And I may be mixing up SERVICE and ORIGINAL parts -- this is not an area I usually judge. I know Reba knows the answer because I remember talking with her about her 1972.

My original cap was dull cad with a black rubber gasket in the ring.

I had it replated accordingly for the restoration.

Car is a April 72 assembled.

Joe, the 1970-1972 JG states black rubber gasket.

Re: 72 gas cap question- Joe L.

I will look at gasket it appeared to be cork but may indeed be rubber, I thought the same as Terry with the gold diachromate , but it has the original plating- dull silver, smooth outter ring and smc marking. I think it maybe possiable replacements were the diachromate.I did look again at gasket, it is rubber.

My original September 13, 1971 assembly '72 has the original gas cap, cad plated (dull silver) with a black rubber gasket.

Re: 72 gas cap question- Joe L.

the original was dull cad with black rubber gasket. the replacements, that you can still get today, are gold dichromate. i have a nos cap that is dull silver cad. the old original cap on my 72 is also dull silver cad. the same goes for the cap on my 70.

Re: 72 gas cap question- Joe L.

The current JG books say '71-72 caps are straight dull cad with black rubber gasket (early '71 have 'Caution Open Slowly add-on label while late '71 and all '72 had this warning embossed) and '73 is the first call out for caps with a dichromate wash, gold finish...
