Yea, I shaved the calipers on a '78 F-250 dana 44 to accomodate some 6 lug weld wheels made for a 2001 Chevy, Clearancing can be done. I just dont know the I.D. of the wheel I will choose, and the O.D. of the brake caliper, and Im guessing I will have to have special backspacing aswell. Gonna be interesting.
I belive they ran Goodyear GS-A's until about 2002 or 2003, maybe even more recently, because I think they switched to the MT/R's in the past 2 years or so. Cant wait to see some pics of the real tires though.
