74 power wagon dream truck...

Call transmission exchange today which is a local transmission supply house. They said the big block short shaft is a 72 and the really nice condition parts small block long shaft 727 I have is a 75... I opened up that 75 and got a part out of it for the small block short shaft transmission I have in the truck now. When I opened it up is very clean inside and I'm hoping to use most of its parts. We're standing the obvious output shaft...
Anyways I called on a heavy duty rebuild kit with the better clutches and steels. But more so I got the information that most parts would be interchangeable. I'll try and dive into them this weekend and maybe get the rebuild kit on monday.
Course my plan is just to rebuild the transmission for now and set it over in the corner. It may be a couple years till I get to it but at least it keeps my hands busy while I'm saving up for the stroker kit for the engine....
