I'd put in rivnuts (as Jim suggested). There's entirely too much danger of
epoxying the bolt into the nut.

That's what I'm hoping for... I'll have to see what he has available
and make due with what I can.

To answer Fred's question, the screws are affixing the trays... I'd
use his mouse, but the poor thing was helping hand prop an old Piper
Cub, a couple of months ago, and wasn't following proper procedures...
If you've ever seen a rodent penetrate a sheet metal hanger door, you
wouldn't be surprised if I told you it was quite a mess!

Thanks and Best Regards,
Todd
