The correct AC Delco distributor cap is the D308R. This cap was used on all Corvette V-8's from 1962 till 1974, and some earlier Chevy V-8's. The caps originally said "Delco-Remy Patent Pending" on the top of them, but the cap currently available from Delco has no markings on it. There is a repro cap with the correct markings on it available from most Corvette vendors for about $50.

the same cap was used on ALL Chevy V8 cars and trucks and maybe International trucks with V8

That is not totally correct. The L88 & ZL1 used a dark brown cap. For the OP, the cap would be black With Delco Remy Patent Pending in a circular pattern around the center tower. Some original caps may have a R after Patent Pending. There should be a reinforcement that runs vertically about 3/4's the way up the right side of the window from the base of the cap.
Looking in eBay, there are a couple used caps with Patent Pending, and many with only Patent followed by a series of numbers. The ones with Patent Pending say the application runs up to about 1967-69 depending on the auction. Are they correct? Since I may have the car NCRS judged some day, I might as well get it right the first time.
Which one is correct for my ‘70?
Thanks.
