I looked at my 02 caliper brackets compared to the 03+ and they were different. The 03+ had a larger distance from the axle mounting hole to the caliper mounting hole which accommodates the larger rotors. Otherwise the larger 03+ rotors would probably strike/rub the brackets found on my 02 from the factory.another tid bit
2000-2008 all have same caliper (dual piston).
My XD's fit my 3rd gen, so I cannot see why they would not clear on a second gen
not confirmed but the 00-08 caliper brackets may all be the same(size wise part numbers may be different). I tossed mine before checking to see if this was true
You, dear readers, may test-fit to your heart's delight, but I'm pretty damn sure that the newer brackets are the key. You could source just the brackets and re-use your calipers but there is no success to be found with changing the calipers and not the brackets.
I do agree that the calipers seem to be the same from my 02 to the 03+.
