Thanks for the replies. I am doing a full on restification of my Dad's old d100. It is a club cab long bed. I plan on building a torque monster 440 and using it for towing my car hauler, hence the brakes. 3/4 ton uses a 1" bigger rotor but the same caliper. I will probably just stick with stock as I have a set of 15" rallye wheels I could use on it. I have had good luck using performance friction carbon metallic pads and it turns out they make them for this application. I will let everyone know how they work- probably about 1 year from now!
