They should still bolt up, the knuckle did not change so the distance between the bolts will be the same. 
 
When I had my 02 RS, it came the newer style pad/bracket and I converted it to the early WRX caliper brackets and larger WRX rotors.  Everything worked fine, I just bought a set of the older style pads.
