What are the differences in diameer & width, if any, between brake rotors on '91-'93 164's and the '94='95 model years. Also, any differences in brake calipers between the two model year groups?

I'm running '94 LS calipers and rotors on my '91 L. They are slightly larger calipers and the rotors are thicker. They are a nice upgrade, really give the brakes a bit more muscle. Simply a bolt on ordeal with only a slight bending of the rotor backing plate to make the larger calipers fit (or swap the backing plates over too). Pads are supposedly the same though I have seen them listed as being different. If anything, the 94-95 pads are thinner to allow clearance for the thicker rotors (but I don't know for sure). They are the same shape and should be interchangeable IMHO. No clearance problems with my stock L wheels.
