There are two styles of TKO input shafts, factory length and shortened. The short input transmissions have had short input shafts installed along with shortened input bearing retainers. When they shorten them, they cut the end off the pilot end, extend the pilot further down, and respline the end of the shaft.

It sounds like you used a regular length TKO, but just had to whack off the end of the pilot so that it wouldn't touch the crankshaft. Sometimes, in certain cases, that has to be done.

If you could tell me exactly which bellhousing you're using, I could give you a better idea of what you're looking at....Quicktime (RM-6056 or RM-6057), Lakewood, etc...
