I have the rear window channels out of my doors as part of my restoration process but now find that one is missing the lower speed nut(s) and the other has 1 of the 2 screw holes stripped. They are unique double screw speed nuts that I am not finding available from the typical sources. One of the holes can be addressed by the use of an over the counter J type speed nut but the other is too far from both the bottom and side edges to allow a standard J type speed nut to work.

I am sure there are a lot of ways to get something to work but wondering what others have done before I try to reinvent a solution.

I know I can buy new channels that have the speed nuts but would prefer a more cost effective solution.
