OK, thanks Kurt. Now according to that bulletin, my car (Fisher body 11D build with T1120HB engine) should have come from the factory with an 1108361 starter. Then it might have been updated to an 1108420 after 12-23-68 if the previous owner had hard starting problems when hot. Now for the second part of my original question, did these starters have aluminum or cast iron noses? We know that after a re builder gets hold of a starter, it can have either and any other parts they see fit. What was original?? Thanks.
