i have a 65 with a 302 crusin bout 900 miles. the temp this week has been in the 100's and i dont have A/C. I have the factory compressor, mounting bracket and interior unit that i want to install. ive heard about aftermarket a/c kits. anybody have suggestions on this or should i do all factory stuff? im 20 and like to drive fast so loosing to much power and gainging to much weight is a factor. thanks guys.
