Here is the back side of where the bolts come through. The plywood is already removed and the wood texture is actually molded into the foam after it hardened. The hard foam takes up the space in the fiberglass mold so when you tighten the bolts there is something to support the pressure. You can see one of the bolt holes in the lower left where the foam has been removed. The foam hardens about as hard or harder than drywall and makes a hell of a mess when it oozes out.
Removing the cockpit panels is simple compared to that repair!
This is the only photo I have on my laptop, I will see what else I have when I get home.

Well, now I can see why tightening the bolts isn't going to help much if the foam is disintegrated. Hmmm....
