Has anyone been able to install A/C in a 70 challenger 440-6. The body was originally from a 318 with air, it came with what looks like everything I need except the compressor. According to my manual, A/c was not available on the 440-6 and it is pretty useless as far as pictures, etc goes anyway. Can I use the stock crank pulley, belts, brackets, etc? Any recommendations? Heat Index has been over 100 here this weekend - A/C would be soo nice right now.
