When you say you can't find neutral, do you mean the gears grind when trying to go into gear with the clutch depressed, if so I ran into that when I swapped in a crank that had the tranny pilot shaft hole drilled to depth, but as I found out later was not honed to size, the crank pilot bushing seized on to the tranny input shaft and kept it spinning even with the clutch pedal down.
I do know (so I've been told) that the engine is original to the car but the transmission is not (it was a 3 spd car) so I think pilot bushings should be ok. Again I'm going to have pull it and see :BangHead:
