On the rear Dana 80 in my 1997 with disc, my parts store did make a mistake of sending me 2008 caliper/bracket kit. When I assembled everything, I noticed that I could use the 2003+ rotors and caliper kit if I had 17" rims. They are a direct bolt on. The caliper and pads were half way off the factory 2002 rotors.
I just sent the brackets back with old calipers as core and used the 2008 calipers on the old bracket. Now I have 2008 calipers on a 1997 truck![]()
