'83 - '88 Door Panel Repair?

[DirtBronco]

As with most 1st gen owners, my door cards have reached the end of the road and are in need of replacement.

Luckily, a pair of compatible XLT/STX/EB door panels with manual windows fell into my lap.
Problem is: I can get the stains out with a handheld carpet cleaner, but the structure has become warped from water damaged.

Does anyone have any experience with refurbing these? Or is there a way to potentially flatted the out the backer bard?
My first thought was an ironing board and steam but figured that would separate the fabric from the board.

I would hate to buy a bunch of new retention clips and install only for the problem to exacerbate.

I'd say the iron is worth a try...
If it doesn't work you'd be looking at making something anyway right?

I have the basic flat style and have considered making new ones from hardboard. Luckily mine was mostly at the bottom so I just stapled some diamond plate texture plastic over it. And I just realized I don't have a picture of that...

was considering a generic board on my old panels but I like that these go over the window slot and give a more complete look.
