As some of you know, I had a slow water leak in my cab and I eventually resolved the leak by removing the old cowl sealer and sealing it back up again. To date, the leak is fixed.

it's now time to put things back together. The headliner is sagging a bit, not just the fabric [that would be easy to resolve] but the actual cardboard backer. There are ABS plastic versions and I am wondering if anyone has had any good luck using them? Is there a brand any better than another one? Any to stay away from?

Just looking for experiences from others.
