is there a difference in rotors from the 91s to the 03s they look real similar but i would think that there different.kind of a stupid question but i have brand new rotors for a 91.

I m pretty sure at least with the 4x4's that the calipers and rotors are 1" bigger in 02 then 01.

I m not sure of 2x4's

i think the newer ones are bigger

your local auto zoo can give you specifics.
