Re: Alternator/Starter part numbers
I don't know if this will be of much help since I'm an Oldsmobile guy, but I have a starter with # 1108794 7C10. It is off of my 1970 Cutlass Supreme SX Convertible with a factory 7.5L 455. Here's some more info....The car is undergoing a complete frame off and so far all of the Date codes and numbers match. The alternator is 1100791 7C21. I mention this because the car was assembled in August of 1969 and the date codes for the starter and alternator appear to be much earlier (unless I am reading them wrong). If they are not original, than it's extremely odd that they would be 11 days apart.
Although I'm an Olds guy, I did help restore a numbers matching 69 COPO back in 1998. Does that give me any street cred?
Best of luck,
