7 1/4 axle shafts needed...

The housings are different between the small and large bolt pattern axles. The axles do not interchange.
I have both small and large bolt pattern 7 1/4 axle housings, and parts. I also have one set of SBP axles that have been redrilled to LBP, but they are for a complete housing assy. I want to keep that for now.
