    How Will My Square Body Look With XX Lift and XX Tires?

    fenders? I like the combo. I was hoping to do a 4" suspension lift with 36" tires, but no one makes a AT tire in 36" (gota worry about ice and snow here). So i guess I'll have to get 37's, but will they rub with a 4" lift?

    Wiring This is a wiring problem, most likely at the fuel tank selector valve setup on the passenger side underneath, as you know. I had that same wonky issue and was sure my setup was bullet proof and i traced all wires for the tanks finding nothing. I went to the selector valve armed with...
