I'll send a picture out of what I'm thinking tonight. It's basically a
1/4" thick plate, 1.5" wide and ~12" long. 6 holes with bolts through
them going to nut plates like these:

, then repeat for the other 2 sides of the rail. The ones you sent out
go inside the rail slot, but would still likely need some sort of
external support for our application.
