1972 Duster swap

[Rick72Duster]

I just bought a 1972 Duster with a six automatic. Here are some swap questions:

What whole rearend from what vehicle will swap in to give me bigger brakes and 4.5" bolt pattern?
Are there any factory exchanges like a Volare that might give me disc front brakes and larger bolt pattern?
How do I identify what tranny I have? I want to swap in a 360 or big block. What tranny do I need?

Thanks for any help.

You need 1973-1976 A body 8 1/4 rear. This will give you the large bolt pattern and GREAT gear selction. You will need a 1973-1976 A body mopar. This will give you all parts for disc brakes, And spool type K frame. Donor car even if 6 cylinder K frame can be used. They make motor mounts for ANY engine size, that can adapt to spool type K frame. Good luck
