Look what I found! I was perusing ebay one Sunday morning, a couple weeks ago, right after someone listed this alternator. It's the exact one I needed for my car. I emailed the seller and asked him what he wanted for the alternator. He said $50. I had him send me a paypal invoice and I bought it immediately. It arrived today and I had it tested at the auto parts store and it works fine.
It's a 1101015 80 amp with a 1M14 date code. If I deduce correctly, that is December 14, 1971, perfect for my Jan 11, 1972 shipped car. This is a real oddball piece since they only came on the Firebirds with A/C and electric rear window defogger with the heating elements in the rear glass.
I disassembled it this afternoon and I am soaking the case in the trusty old Purplestuff degreaser at the moment. I found a new front bearing for it in my box of alternator parts and it should be good to go.
