Hello!
I'm making slow progress, but all progress is progress. Anyway . . .

I riveted the floor in place, very effectively. It was pointed out that may be an issue with the seat brackets, and I MAY have to drill them out to do again. I don't want to have the issue of drilling out rivets, because sheet metal is in the way for a later step.

Any suggestions about which panels should be attached with rivnuts instead of rivets, so I can get them off later?

Thank you as always.
