5.9 magnum automatic crank

That was my next question. The difference between the bushing and the bearing. Is that an either or type thing can I choose or does it depend in the transmission shaft and or crank ID?

If it's not drilled for the bushing, you may have to cut some off the tip of the input shaft, I am not sure. I know in some cases with the older stuff you had to. OR have the crank drilled of course.
