Well don't let them fool you. Buying just the caliper and disc is going to be a problem. The spindles are different. You need warrior or banshee spindles or 03+ blaster spindles. Without them you will have no where to bolt the caliper. So what you need is left and right spindles from a banshee,warrior,03+ blaster then you need calipers, discs, and hubs from the same three bikes, then you need a front, master cylinder from any yamaha quad that has front disc brakes. And of course you brake lines.
