rear bumper clearance

[IdahoBen]

Installed the rear bumper and have excessive side clearance.  Over an inch from the fiberglass to the mounting pad on the bumper.  I think I need to bend the bumper.   What is the standard gap?  As it is the bolts do reach.

There’s a 1/4” rubber shim that fits in between the bumper and the fiberglass body which will fill some of that gap.

The gap on your Avanti does look excessive.

I’d add a second rubber shim, then tighten the bolt to crank it in.
