The 2 small holes are for holding a cleat. The threads in one of them are gone. The screw slip right to the bottom. I'm considering an helicoil to fix that.
fill with cold weld/JB weld, drill & tap.
glue a coupler in same products
you cannot get at it from the bottom?

I have to disagree with the Bondo. It has no place on a boat and isn't all that great on cars. It's too porous. West System with silica filler in the holes then coat the fasteners with mold release wax, a clean thin coat, and thread in the fasteners. Once cured the epoxy will be threaded. If the fasteners get bound heat them with a soldering gun. They will release.

Okay. What I didn't told you is the threads are in a piece of metal, probably aluminum, laminated in the fiberglass. That's why I was thinking about helicoil. I'll see if I can find them in the #8-32 size.
Bondo-glass is not really a mastic like the ordinary bondo. To me It's more like thickened polyester resin mixed with short glass fiber.
The trouble with Bondo is it's light on the resin and heavy on the filler so it can be sanded easily.If the holes in the metal are stripped out take the size up to 10-32 or larger.Then use some kind of epoxy. The JB Weld recommendation is good. Marine Tex is good. Bed the cleat with 3M 5200. Good luck, GH
