Chassis Help

[68CRUZR]

Hello, I just purchased a (1957 Cab / 1959 Fleetside Bed) Truck. Truck runs great and looks Awesome it is however on a 72 Chassis. I like the fact that rear are coils vs leafs, frontend is all rebuilt, already has pwr steering/brakes. Biggest drawback is that fnt wheels are not centered in wheel well. They sit about 3" towards the rear when looked at from the side. Also they stick out about 1/4". Obviously this 72frame/bed,cab is not the best set up. So here is my question around the frntend, "Can I fix this problem?" I want wheels in and forward, maybe with a Mustang II or some other IFS system up front? Only thing I really want to achieve is to drop truck (bags). I've been searching for the specs on a 1972 chevy truck chassis but haven't had much luck. Any info will be much appreciated, Thxs.
