I have an NOS gas cap that I can't find in my books. I see a few of them on ebay etc and most guys are claiming this cap fits 64-70 Chev Olds Pontiac Buick. Does anyone have a GM publication with this number in it to confirm that?
It looks like this underneath.
1966 Strato Chief 2 door, 427 4 speed, 45,000 original miles
1966 Grande Parisienne, 396 1 of 23 factory air cars (now converted to a "factory" 4 speed)
