Ok here's what I have. Front rotors from 1996 1/2 ton Z-71 4x4 6-bolt, turned and now have surface rust. New pads for same truck and Hypertech programmer. It will allow adjustments for tire size and rear end gears, as well as shift points and performance. I would like to get $150 out of everything together. If interested I can post pics and I will get #'s from hypertech box also.
