I have a 1100928 closed face alternator with a December 1971 date code "1M14". This was a leftover unit from my old 1972 Trans Am.
Bearings spin freely and the internals look nice but I don't have a way to test it for voltage output. It did work when I removed it (in order to replace it with an open face version).
$100 plus shipping
