Two RS dash-windscreen questions

Almost done with my RS restoration and have a few questions wrt dash / windscreen.

1: I bought, because it's in the parts fiche, the thin roound (in cross-section) gasket or sealing strip that apparently does somewhere under the dash to prevent wind leakage. Part #20 in this diagram: https://www.realoem.com/bmw/enUS/showparts?id=0377-EUR-03-1980-2474-BMW-R_100_RS&diagId=46_0085.
But I'm having trouble figuring out how to install it and at what point. There's no corresponding groove anywhere that it might fit into. In reply to another of my postings, Steve Rankin said he doesn't have one of these on his RS, maybe it's an RT thing? But it is in the RS fiche.

2) I'm wavering between rivets for the dash versus plastic screws. I don't have a riveting tool, but I might be able to borrow one from my mechanic. I *do* have the plastic screws however. If I go with rivets, and following Brook Reams' site, I'd rivet the dash to the upper fairing, then screw the windscreen through the dash. Same plastic screws? I would think that the rivets holding the dash to the fairing would require smaller-diameter screws because the rivets will take of some cross-section.

If I go with the plastic screws (which is the most likely course) I'll have the mount the dash and windscreen at the same time, because the screws that hold the windscreen to the dash will also hold the dash to the fairing.
 
I seem to remember some discussion about putting the fasteners for the screen. They were rubber and had to be pulled into shape. Not sure I could find that earlier discussion.
 
After riveting the dash to the fairing, I could see where this rubber gasket string goes. The dash-fairing interface leaves a sharply-defined gap which is just the right size to push the rubber string in along the front and around both sides, as in the pics attached.gasket1.jpggasket2.jpggasket3.jpg
