I agree must have v8 k frame . What engine did it have when you looked at it? If it had a 318 then it has had a k member swop, which is good for you ,it will save you alot of work. Also check torsion bars, you will need the BB bars for the weight and torque. Yes I would up grade to 8 3/4 rear end or if your not worried about keeping it Mopar find a good Fd 9". Personally i would keep it Mopar , maybe even think about a Dana.:thumbup:
