Mopar had a roller bearing and a bushing that fit into the torque converter pilot area of the crankshaft , but I don’t know if it is still available ------------------------ It doesn't matter what you do.........As long as you look good doing it !

The needle bearing for the converter register is Timken fc69907.

For switching a automatic non drilled crank over to a manual transmission application. Does anyone know if this bushing is still available? I'd heard rumors of the needles eating into the input shaft of a manual trans. designed to ride on bronze.

Mopar 04338876 ought to be what you are looking for, unless it's been supplanted by the roller version.
