Cutting A833 Input Shaft Question

That is the type of bearing I’m using is the one that goes into the convertor register. I’m a dumb redneck from Wv. But not dumb enough to try and drill a perfect hole that would hold a pilot bushing/bearing laying on my back with a drill. Lol. I wanted to just make the existing hole a little deeper so I didn’t have to remove as much of the shaft
Yes, use the roller bearing in the torque converter register. Install it, carefully measure how much to cut and do it. The shaft only needs to be long enough to go through the new bearing.

After cutting, grind a lead-in chamfer on the end of the shaft like the original.

Some of the pictures show drilled but not reamed holes. Reaming for pilot bushings may actually have been done on the assembly line.

Nice car by the way!
