I have a 77 mav the came with factory a/c. but i've dropped in a 91 5.0 motor the s-belt system. Is there a way to make the 91 a/c pump work with the 77 mav hardwear.
yes you just need to take the ac hoses for the roller motor and the ac hoses from your car and have the ends changed on them. any ac shop should be able to do that. then just put the power wire on the compressor.
