nope, pre 03 spindles do not have a caliper mount
and i just had troubles with yfz hubs, the inner bearing is smaller and would not fit onto the inner race of the norman420 built pre 03 spindle with caliper mounts.
you can fab/weld caliper brackets, but the norman420 units have proven to be tits, then stick with banshee hubs and brakes, easiest route IMO, i've done 3 sets
