Tire and Rim Ideas 71 Valiant

I just picked up a 71 Valiant and I'm looking for a Tire and Rim combo to put on it. I'm trying to come up with Ideas on what will fit, I want the slight 'Drag' stagger size look (smaller front, bigger rear), but of course I want to go the cheap rout and keep the stock rear end and suspension, I'm just going for the look. I had Cragar SS's in mind with probably BFG Radial TA's.
Anybody have any Ideas on sizes? I'm trying to squeeze the largest tires on the rear that I can fit with out too much modification to the suspension. Also rim size and offset???
