The driver seat back 4 screws ripped out yesterday when I hit some big waves. I can only guess that my weight must have at some point over time been leveraging the seat high on the seat back or the force would be straight back and not be pulling tension.

I pulled the seat back off and there are some type of inserts in the fiberglass. Anyone seen these and have a recommended way to repair? I'm thinking since they ripped out they won't hold again under even less sever conditions. My first thought is to inject the insert with something that will give the screws more bite but stilll allow for removing the screws.
