5.9 magnum automatic crank

Now, if you did that, wouldn’t that make the trans only good for that undrilled crank and to short for a normal manual trans crank?
I have to find a illustration breakdown of the input shaft and clutch assembly. I'm not sure what the difference is between the bearing and the bushing the bushing sets inside of the crank for the input shaft to set in. Where is the bearing in this setup? In the clutch itself? Or on the outside betweens the clutch and the flywheel.?
