28 Roadster floor/curtain pan

[Beecher]

Im starting to build a 28 roadster, but the subrails and floor are all brookville. Im in the process of getting it all fitted together now, but have a couple questions before I can proceed.

Firstly, the curtain pan, it rivets to the number 2 cross channel, at least on the front edge, but what about at the back edge of the cross brace? It would make sense to me if it was, but Im not sure. It is an original cross brace, and it does have holes in the back edge, but thought that could be for a non rumble car? Mine will be rumble

Second, the seat stiffener brace, I need a picture of this piece installed. I cant figure enough of it out to feel comfortable enough to trim and install.

Third, I assume the front edge of the rumble floor gets rivets across the front seat rear riser?

I know there is a great thread on here with the assembly of the 30/31 floor, which has been a tremendous help, but a couple pieces arent the same.

Thanks so much everyone! This is my first A, so another big learning curve.
