WA WTB 61 AMP alternator with date code - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Looking for a 1972 date coded alternator. These 61 amp alternators were used on all trucks with AC and others that ordered it. I need it for a restoration so the date code would need to fall somewhere in the 90 days prior to November 20th, 1971. The part # is 1102455. See the example in the attached photo. The date code is 1 J17 for the which translates to October 17, 1971. I would prefer one in the range 1J1 to 1K20 but could work with one a little earlier if that is all I can come up with. Thanks, Chuck
