Grinding 1 Ton calipers, for 15\" wheels, again probably........... Well I'm at that point, i'm trying to fit 15" wheels, with a 3 1/2" backspacing on a 1 ton axle. I've tried doing searches, but most things come back with nothing. I tried Wayne's "Mighty Mouse project", and get the dreaded blue screen. I guess my question is, where in the caliper do you grind? The top? The front edge? All of the above? Help guys! And, again THANKS!
