I'd like to know if the splines on the input shaft are too close to the pilot bushing. That bushing has been modified for a reason, know what I mean?

I'd hate for you to pop a new bushing in and then find that the input shaft is bottoming out on it.

Anyway you can put the bellhousing back on the engine without the flywheel and clutch, then measure from the pilot bushing to the flange.......then measure from the transmission flange to the end of the input shaft (both to the splines and then to the end of the pilot)?

See what I mean? I'm probably not describing this well at all.
