The Ford Barn - View Single Post - Help 33-34 draive shaft in shortened 40 rear end tourqe tube

I purchased a good front stub from a fellow barn member. I think it was removed from a 1935 or 36 shaft but it really doesn't matter which. The front stub spline shaft was just welded in so it was a matter of cutting the weld and removing it. The trouble is finding one in good condition. The rear spline can be made from modifying a spline adapter fitting which are available from the resto parts suppliers. A drive shaft shop can do the tube work and balancing if you have one local to you. The 33/34 shafts are hard to find now days but there might be one out there some where.

I don't know if your solid shaft can be shortened & resplined or not. It depends on the diameter of the end after it's cut. The splines can be cut in a horizontal milling machine with proper indexing for the type of splines so that the pinion adapter can be reinstalled. The damper bearings are available as was already mentioned and the price for them isn't out of line at all. You might consult a machine shop to see what they think. They will need the correct dimensions to do the job.
