Re: Will a 9-A leadscrew work for a 9-C to 9-B conversion (no quickchange)?

For a given bed length the 9a lead screw is shorter than the 9b - the gear box takes up some space. I have seen people adapt the 9a lead screw to a b set up by turning fill in shaft for the tail stock end.

I'm sure this topic has been beaten to death, but I'm still a bit fuzzy on one point. I'm attempting up upgrade my SB 9" model 'C' to a 'B'. The lathe is in very good shape - a bit dirt from disuse, but no real rust, and very low hours. I've purchased on eBay a "model A or B" apron, and a "9 or 10K crossfeed screw" (with the gear that my 9C screw lacks). So I think the only thing I also need is a new leadscrew. Will a 9A (quick-change gearbox) leadscrew work, or do I need a 9B?
