Thanks so much for the ideas fellas. Still working through problems; was able to find an NORS input shaft from an antique auto parts house in Michigan, Buick part no. 1282454 or Perfection part no. WT187-16E (pictured). It is exactly like the damaged shaft from my trans EXCEPT that the bearing on my (bad) input shaft is retained by a C-clip; the "new" input shaft doesn't have a recess for the C-clip, it instead has fine threads to accomodate a retaining NUT. I'm now hunting for a an appropriate nut to use; if that fails guess I can get a shop to machine a recess to accept the C-clip. ALSO, yes my trans has a seriously damaged cluster gear so I bought one from Ebay which was supposedly correct for my '35 40series; turns out it is approx. 6 3/4" long whereas the cluster gear out of my trans is approximately 7 1/4". Not sure if the seller was incorrect of the application or if maybe the trans in my car is from a different year? I've sent some emails, hopefully can figure this out. Any information, ideas or comments welcomed!! Thanks again-
JOHN
