Rear Brake Identification

That would be the easiest way to do it, sure. Set it up like a stock Mopar 10x2.5" brake system. I wouldn't say there no other way to do it, but anything else would probably mean a lot of research and/or custom work on your end. The 10x2.5" brakes were used up until the late eighties on all kinds of Mopar cars and some trucks, the parts are readily available and fairly inexpensive. You should be able to find all the parts at your local parts store, or RockAuto, Summit, etc. Just make sure they're 10x2.5" with a 5x4.5" bolt pattern and you should be good to go.

Awesome! Thank you very much!
