Basically Baer told me they were the same until I asked for measurements (which they say they don't have...) Wilwood actually got me measurements from their drawings and the both the brackets and calipers for my axle housing are the larger size...

So... we were going to do the big brake kit rears for the 2500HD and swap hats with teh BB rotors for the 1500 kits. Doh! 1500 kits are 1 piece rotors.

Kevin at precision is trying to get the 2500 rotor hats undrilled from Wilwood and then drill the lug holes for me. however, we don't know yet if Wilwood will sell them undrilled. If they do, great, problem solved. If the won't, I'm looking either a custom bracket and caliper, shimming the rotor itself or burning the truck
