I am having issues. I have a 94 model. So, it could be the fiberglass is just old. What is happening is they will work fine for a while and just rip out the fiberglass. I have tried adding epoxy to the back of the adapters along with the screws and it still does it. I put it to a new spot each time. I even tried thicker screws. I don't know if there is anything like you put in drywall for strength. Maybe, like the plastic pegs. I don't really want to go all the way through but am about to that point. Just wanted to check first. I did even drop all the way down to 10 lb. struts on the big lids incase it was too much pressure and it still did it. Any ideas?
