dream68 can you elaborate on the 88 truck you got the parts off of. Was it a 1/2 ton or 6 lug 3/4 ton? I have Hollanders on my laptop and would be able to post some info for folks. Hollanders does show the 67-70 vs 71-87 3/4 ton lower control arms being different. Which did you use? I have heard you could use the 88-91 3/4 ton 2wd 6-lug rotors on 71-up spindles using 71-up calipers. I went to Autozone and had them pull a 71 1/2 ton 5-lug rotor and a 88 3/4 ton six lug rotor and they were basically the same and appeared to use the same bearing.
