Well since I got new pads with my truck I've been looking to do rotors. I hate doing one without the other. I found a company I've used before that makes zinc plated drilled/slotted rotors makes them for the MM/D50 Theyre asking me if it has 9.5" or 10" rear drums saying it makes a difference in the rotors. Has anyone come across this before? I can assume the 9.5s will have larger rotors but is there a way to check without taking everything apart?
