stupid rearend question

[Bandit72]

ok, i currently in my parts pile have a complete rear-end assembly out of a 65 dodge shortbed truck with 3.91 posi gears (mopar 8 3/4), but like i say this is out of a pickup truck. besides having to move the shock mounts and leaf spring "pads" will this work or be too narrow, i'm thinking it'll be way to narrow but i figured i'd check before i go and find an assembly out of a 71-72 B-Body....

thanks Bandit

I think a truck one is wider than a car.  I could be wrong usually they have to be narrowed a bit and with the other things you noted I now the leaf pads need to be moved.

Unless you want to run very skinny tires, you'll have to shorten the axel tubes which also means you'll need new axels...might be cheaper just to find a cheap B-body 8 3/4 rear axel (like with an open 2.76 in it...use this "horrible differential" as leverage at the wrecker yad..."Man, a 2.76 open...that's horrible!  I'll give you $50 to take it off your hands!") 

Then you can  transplant your 3.91 Sure-Grip pig onto the B-body axel...might be a cheaper way to go with less messing around.
