Hi I wasnt sure if I posted this right. Good day I have a 1970 36 sedan and the entire bridge sagged, I took the liner down, found the bridge has foam core ribs both ways. I jacked up the bridge from below in the center, then I took 1/4 inch strips of mahogany and layed biaxial cloth and epoxy resin and screwed them to the beams I did this four times. once this hardened it formed a slight dome in the bridge when I jacked it up therefore the fiberglass doesn't bend the other way once hard. I relined the ceiling, and I have had up to ten people up on the bridge and its been five years and no problems yet. It was a pain but it worked for me. I hope this is of some use to you.
