Those should work, I have 4" back spacing front and rear with 6" and 8" width. I also have the posies rear springs, rides great...and the wheels are centered.
Well I retrofitted a 8" wheel with 4.75" bs and a 10.5" tire and the tires are about 1" into the inner wheel well. A friend is bringing a 16" mounted wheel over tomorrow to get some measurements. I'm still gunnin for 17". Onto the king pins, never done ' em b4 n these are froze up! I used my OTC ball joint tool and it made it much easier
