will these bolt up to the 03- 06 blaster spindles?

Pretty much ALL japanese sport quad (and even some utility) calipers are the same bolt pattern. The choices are practically limitless as far as the calipers go. The hub is a little more specific. You need 03+ blaster, 99+ warrior, a-arm banshee (90+), or certain year YFZ450 hubs to work on either the norman420/KOR or 03+ blaster spindles.
