I have a 1977 Chevy Nova Concours with a 4.1L 250 L6 and the AC is only blowing warm/hot air. I was wondering which parts I'll need to fix the AC so it could blow cold air? I suspect the AC compressor and AC clutch adapter are due for replacement but I am unsure if there are any other parts I'll need for a full replacement. A complete list would be preferable.

What makes you think the compressor needs to be replaced? Is it making noise? Is the compressor clutch not working?
Has the AC been converted to R134a? What are your high and low system pressures?
Don't just throw parts at the problem. Perform a proper diagnosis first.
