you shouldnt need to grind the spindle because the bracket holds the caliper further away. reason it is needed on the 99+ v6/gt brakes is because the caliper is at the same height as the 94-98 gt/v6
www.discbrakesrus.com sells the basic kit for about $400 too. They also have a lot of options as far as powdercoating in a few different colors, slotted/drilled rotors, etc.
