Used GM Delco-Remy Alternator, casting #1102369. Appears to be correct for 1969 - 1975 Camaro and Chevelle, along with 1973 and 1974 Olsmobile Toronado and Cutlass. Last number of date code is difficult to read (3*H*4?). 63 Amp - 12V - NEG. Unit spins freely, but should probably be rebuilt. All mounting points and connections look good. Pulley is about 2-9/16" in diameter. Good Condition! $45. Will ship!
