Non A-body question.

I have yet to get a motor and trans for my 65 Cuda but I have found a deal on a possible parts car with a 318 auto, and the guy also has a running (according to him) 318 in his shop. I don't know the exact year of the parts car but it looks to be an early to mid 80's Dodge Diplomat 2 door. The price he wants for the 2 motors and the trans that's in the car is very reasonable but for a few extra bucks I might be better off dragging the hulk of a Dodge home and tearing into it. Is there anything I can use off this car that would work on my 65? I'm thinking stuff like parts for a front disc brake swap, maybe the rear diff? What auto was in the parts car and would it fit in my Cuda without having to butcher my trans hump? If none of the front disc stuff will work for my car I'll probably just buy the 2 motors and one trans off the guy. Sorry for what may seem like dumb questions but if it were an A-body Chevy, I wouldn't be asking them because those, and Tri-5 Chevys I know about. Just a Mopar newbe now.:-D

Thanks in advance for any insight you people can give me here.:thumblef:
