Seems the key to making TUTS 59’s setup work for different years and weight ratings is hub size of your model. Haven’t taken my 54 2 ton apart yet to get exact measurements but the rough crude measure I did with wheel still on tells me my hub is very similar in size to fit a tilt master rotor. Of course crude measure is not good enough, so maybe if everyone measured their hubs from different years and weight ratings we could get a list going here with what rotors can work on our trucks. Thanks TUTS 59 for sharing your fix, hope to put it into use at some point.
