Depends on your budget, you can go with used ones off another blaster you of course will need the calipers, brake lines, mastercylinder, and the brake hubs and spindles, your a-arms are the same I believe so you would not need them. I would check e-bay or cycle salvage places for used or post on wanted here or if you have lots of money check with a Yamaha dealer. Me and 01_blaster freak just swapped all that stuff from my bent 04 frame onto an older style frame I had with no problems. If you have the parts it probably would not take you more than a couple hours at most to do them if you are mechanicall inclined.
