The car is 1972 Mach 1 with AC, 351C-4V, build date is 03/16/72. I've purchased parts from two different sources, neither one correct. The gauge feed harness is short one jack and the alternator harness has the metal locating tab in the wrong location and the gauge of the Black with orange stripe wire is 10. It should be 8 gauge for a car with AC. Any help finding a source for correct parts is appreciated.
Thanks, Chuck
