I bought some door sills for my 67 from YearOne. I have no carpet in the car and plan to carpet it.

I will describe what I'm looking at:

Since the car used to be a race car, everything was taken out for weight savings. The carpet is gone and its bare metal on the floor. There are holes in the floor boards with plugs or plates of metal that obviously go in there. The plugs are glued down or something, except one. Its loose and when I pick it up, you can look through the hole right to the ground.

Should I glue that down or screw it down? and with what do you recommend?

OK, here's what else....
Where the door sill goes, just inboard of that is a metal rib that is about an inch or so tall and runs parallel with the door.
Is there something I'm missing here because the carpet doesn't lay flat with that rib there. I've felt the carpet in that area on Camaros that are finished and it feels like there is something more there. Like more metal laying over that rib.

What am I missing?

Glue the plug in place , thats how the factory did it. I think they used seam sealer thats how I glued mine.As far as the sill plate areas are concerned there is a piece of rounded sheet metal that screws in along the length of the sill area that forms the carpet neatly up to the sill plates I dont know exactly what they are called but they are supposed to be there.I'm not sure if they are available either you may have to find them used somewhere. Hope this helps.

Can someone point me in the right place for these? They don't appear on Ground Up. Maybe I just don't know the right name for the part number.

This is what I need.

I think that's what he's talking about as well.
