Mike c....thank you for answering all my questions. It really helps. Do you think I need to do anything with the yoke now (hope I’ve got the terminology correct. I’ve rebuilt an engine but never opened a rear end until now!) I assume something custom will be necessary to get power from the output of the 4l80 to the original 12 bolt?

I haven’t researched the options for this yet as I felt it would probably be a bit before I got the engine/trans mounted and connected to the rear. As A note, I do have two original driveshafts. Both trucks were manual trans and I also have the original shaft from the 2001 2500 hd donor truck.
