Hello Rob
Fronts are 15" x 4" Direct Bolt Cragar's with 5.60.15 Pro Tracs which measure 25.8" tall and have a 4" tread pattern with 5.9" section width. I'm not sure the backspace on the fronts but just checked and it looks like 2" or something along those lines (may be 1-3/4"). No issue at all clearing the single piston front calipers on the 69 as you can see from the back shot. Hope that helps you out.
G.
