tranny swap
 

I have two e40d ford diesel trannys, one came out of a 94 super duty, dually, this is the good one, the other came out of 92 f250, the bad one. The good one came with two piece driveline and bigger ujoints, and the tail piece is different. It seems to me, if I could take the shaft out of the bad one and put it in the good one, it would solve my problem, it would fit, right?
How hard would that be?
