72 Dart Question
 

I want to do a large bolt pattern swap on my 72 dart. I found a 74 duster parts car that has the front disc brakes and rear end. I know the front brakes will work but will the rear end also fit? I want disc brakes but I don't want 2 different bolt patterns on my car. I'm assuming that it should just be a simple swap being how they are both a-body vehicles, but I'm no expert. Thanks in advance for the help.

Rear should fit. Take a look under there. Might be a better (larger) or smaller rear. Who knows what the ratio is, but it PHYSICALLY will fit

I tore apart a junker AND my original springs, and used the longest leafs out of both spring packs to make up one good pair of springs which stiffened the rear up some without jacking it up much.
