I have a '73 27' Overlander with the rear bath. I'm in the middle of a floor replacement and had to remove the wall that connects to the sliding door. The header that supports the sliding door connects to the wall by way of a plastic bracket and the wall itself is secured to the ceiling by way of another plastic bracket. They both are in need of desperate replacement. The local AS dealer says their obsolete. Maybe, maybe not. This forum has been a goldmine of information. Perhaps one of you out there knows where I can get replacements or may even have them laying around. I'd love to get my hands on new brackets or ideas on a work around if the replacements are a strike out. Photos attached.
