susan, I see that does say B, BN, A I am thinking it is different Than the later models.

Susan, What Jim was saying is the shaft must be a different length From A to SA. oldiron29

The A and SA would be the same but the B and BN would be different and neither would work on the A or SA So there would be three shafts.
