I would appreciate it if someone could tell me what the fasteners are for bolting the rear bumper bracket to the body on my Barracuda? My bolts are 7/16" dia. x 1 7/8" long with about a 1" shoulder before you get to the threads. They have a heavy washer and a retainer clip holding the bolts onto the bumper bracket. The problem is that the shoulder sticks thru the trunk too far for a nut to tighten up to the body. Is there a spacer of some kind?
