Thanks Doober! No I didn't narrow the rear.(if I didn't have 3sets of wheels I certainly concider narrowing) I use 3rd gen f-body rears that have 5+in offset. Cheap and works well. Btw I using s-10 4wd axle brackets and 2wd rotors. The 4wd bracket obviously mount the caliper on the front of the axle and the caliper is mounted on the back on a 2wd. 4wd rotors won't work and have way too much offset to work on a a-body axle.
