The trunk rack uses the same 2 bolts per side that the rear bumper cross brace uses. The correct order from the outside to the inside (if you have a full width rear bumper) would be: Trunk rack support, bumper bracket, spacer and bumper cross brace.
The spacer is nothing more than a A-17798-A Bracket (rear fender guard bar) cut shorter. See page 4-18 in the Restoration guidelines.
