The reason i am asking is a friend of mine had a 1981 Corvette and he wants to sell me all the shop repair manuals he has for a 1981 Corvette. will this be beneficial to me since i have a 1980 Corvette?
The 1981 manual should be very close electrically, the difference will be in some of the carb/timing and trouble shooting proceedures and diagnois for engine problems.. Unless you have the CA. 305 engine. Then it should be very similar.
Wiring diagrams for the window, locks should be very close too. I believe the 1981 was the first year of the ignition interrupt circuit, so that will be different too.
