I am assembling a 26 transmission. Have on hand a good driving plate with the exception of some scouring on the ball cap / 4th main contact area. I have a crankshaft grinder so it isn’t a huge job to turn the bearing contact area underside.
Which will mean an increase in the Babbitt thickness in the ball cap.
I estimate the diameter will be about .035” undersized.
Wondering if any engine builders have tried this?

Do it all the time, machine the drive plate and increasing the thickness of the babbitt and re-machine that to fit, the early ball caps made by dodge had about 1/4" thick babbitt.

Here is a link to a thread from Herm. Shows how he did a transmission. Look down at how to fix your problem.
