Hello,
I am a DeLorean owner, and as you may know, the D uses the UN-1 5-speed box.

I am rebuilding the UN-1 right now, and my input shaft is damaged (heavy scoring/chipping on the pilot bearing surface). I would like to replace it, but a new shaft will be at least $400 shipped to me. Is there any way to repair mine for less? Some have said that welding it will ruin the heat treatment.

If I could switch to a better input shaft (Ford?), and have it fit in the existing primary-shaft-coupler, I would. I don't mind changing the clutch to one with a different number of splines, if it means the shaft will be stronger in the end. What I do have a problem with is paying $400 for a weak Renault input shaft (I already have 2 damaged shafts).

Any help or insight is appreciated.

thanks,

Matt
