MY 1989 Camaro had screws attaching the OUTER sweeps. The old INNER sweeps appear to have had plastic rivets at one time, now replace with screws. I will try to find 1/8 Diameter plastic rivets and likely add some adhesive.

What say youse?

Screws on the outer, rivets on the inner. Your correct, B=outer, A=inner. The giveaway is the U(arrow). Thats for the adjuster at the top of the door frame
