yes stock 1k rim,rotor ect will work..you will have to get or mod a rear caliper hanger..
I have a few 600 hangers that will work but You will have to ad a tab for the brake bar..I cut the slot off my damaged 04 1k arm for the stock setup and welded it on the 600 arm..
ps.I also heard You need some kind of spacers for where the big bolt goes threw the frame for the arm to work..
