I like the Rivnut idea. I researched this and it's probably the best controllable option. Although I did consider panZZer's idea with the screen and glass. Currently I used polyester fiberglass resin mixed with fiberglass strands. This is called kitty hair. Some patches held and other didn't. I'm new to working with polyester resins so I would either mix in to much hardener and cause it to cure to fast, or didn't put enough hardener in the mix which resulted in something that never hardened completely. My experience is solely with epoxy resins. In repairing any fiberglass repair, it is imperative that the bonding surfaced be roughed up with something like sand paper to cut through glassing and maximize the bonding area. In a small space like where this bracket goes, it's not that easy.
The glue idea I originally had and the 3M 5200 is used in the marine industry just for the purpose of gluing two objects together, just never try to take them apart. Since this is a keeper vehicle I'm going to try the Rivnut idea. I want the option of being able to take it apart if ever the need arises again. I'll supply pic's tomorrow.
