I know free is nice and all BUT if he is giving you that stuff with the stipulation you "HAVE" to use it in your car I would pass on the stuff and look for some cheap or free mopar stuff to use in the car
or find a GM car to use the chevy stuff.
I know its been done many,many times befor but
Me personally,I would never use a Gm drivetrain in any of my mopars, If I had a GM drivetrain I would find a GM to put it in Thats just me



so on to your questions, I have put camaro subframes under mopars but I like the Mustang II style frontends better.
and I don't care for the 12 bolt rear ends with the "C" clips, a 8 3/4 is stronger and better to narrow, but you could have ford or mopar ends put on a 12 bolt, but you need the right axels to be able to shorten them or get after market ones(not cheap) Ron...
