4 speed to auto crank?

I was the one that had recent interference with the step on the input shaft, using the dakota / jeep roller pilot.
With a few other problems.
I have yet to own a small block that was not drilled deep enough for an input shaft.
Some big blocks especally 383 yes.
Still measure what you have.
And if somebody has already cut the input shaft too much to run a factory pilot.
Brewers sells a pilot similar to the roller bushing but it has a brass insert for about 15.00 bucks.

Look here for some problems I experinced, and the step on the input shaft.
