I need a little help from you V8 guys. I am in the process of installing rear calipers on FrankEnSPRIT and have a question. The parts manuals are reasonably complete in this area, with one exception. There is a sizeable gap between the rear brake mount and the brake caliper on the M8 bolt that anchors the bottom of the caliper. There is no mention of a spacer in the parts manuals that I have been able to find. Is anyone familiar with how these things bolt up?
