Check panel falling out

[Beej '86 325es]

My header panel that houses the check panel isn't holding it in very well. The surrounding piece seems to have a bend below the check panel and it's causing it to flex, so the panel doesn't snap in tightly.

Any recommendations on how I can fix it? A fiberglass or sheetmetal reinforcement I guess?

Cloth friction tape around the check panel. Works in almost all cases.

Not a bad idea with the friction tape. Cosmetically, the header panel looks just fine, it's just a little weak.
Thanks!
