Yeah, the rulings on this one have been rather puzzling. The question was actually asked twice last season and the answers conflicted. The upshot was that McMaster-Carr D-shaft is legal but Servo City D-Shaft, due to a chamfered end, is not. That would sort of make sense except that McMaster-Carr shaft is chamfered as well....
