As far as the new model light duty 3/4 ton 92 six lug rotors- yes the are similar, no they do not work correctly. The bearings, races and seals are exactly the same as our trucks, nfortunately when installed they have about 1/8th positive offset at the caliper different from ours. The only way to get the caliper to fit would be to use organic pads and grind them down until the caliper slides onto the rotor. I for one don't like that idea, but the cost for those rotors is cheap, $40 each ,so it may be tempting. I now that there proposals that the difference could be made up by using 92 calipers- they WILL NOT fit. Buy from Pauls or ECE andbe done this is not something to monkey with- I tried based off of info I found here and also had access to parts books and employee discounts when I attempted this. The later rotors DO NOT FIT AS THEY SHOULD with what our trucks have in place stock. Good luck.

Excuse the minor hijack, but, do you know if those rotors would work on 73/87 spindles?
