I posted this in classifieds and I thank the guys that responded. I need an input shaft for the transmission, part number 1S1801. Cat no longer sells a new one.  I have not been able to find a good used one either. Thought I would try on the general forum.   I had a bearing go out on the intermediate shaft and in the process of overhaul found the input shaft splines are worn badly. Anyone happen to have one or know where one is I would appreciate hearing from you. Thanks

Couple of possibilities...

any good general machine shop should be able to cut you a new shaft or bronze up and repair the original. cutting a new one wont be cheap but a repair maybe possible and would cost less. its the labour in setup of the tooling that costs the money.
