18x9 & 18x10 GT500 wheels on a Dart with mods. Is it possible?

This is regarding the possibility of fitting some American Muscle GT500 wheels on a 72 Dart with 73 and up front disk brakes and A body 8 3/4 (or even a explorer 8.8) rear and with 3" mini-tub with springs relocated.
Here are the specs:
Front: 18x9 6.2" (157 mm) backspacing / 1.2" (+30mm) offset
Rear: 18x10 7.2" (184mm) backspacing / 1.8" (+45mm) offset

Not set on a tire size yet or if fender lips need to be trimmed and rolled.
