Congrats on getting it installed. You should not have had to hone the bushing. Did you slide the bushing over the trans input shaft at room temp before installing the bushing into the crank?
Yep, and it explains why I was very surprised that it would not slide in after installation. My first thought was the inner diameter shrunk because the bushing was frozen. After waiting for the bushing to return to room temp, the input shaft still would not go. On the Team Chevelle site, one of the posts described machine work on the bushing. The drill bit was my only available and reasonable option.
For the future a member might try the old school trick of taking a length of 3/8 wood dowel cut a slit across the end and Incert a length of fine emery cloth. It would be easer to handle than a 1/2" drill.
Imho I would think the bushing should be kept as close to tolerance as possible. The input shaft is pretty long to not be properly supported at the fwd end and centered. Im no engineer but the thought of the clutch disk/disks running several thousands off center would bother me.

Use an Autogear pilot bushing and avoid all these issues.
