These are good tips! I'm glad I'm getting a course on repair vicariously through you Jim ! My board is cracked at the visor mounts as well and I was planning on using fiberglass mesh and epoxy for the repair. They make aftermarket boards for us coupe guys, but for $100 I can't justify it when I have the material to fix mine. That $$ can go to new headliner and visor material.Jack, your right about the visor area, they always seem to be in bad shape.
Looking forward to seeing the results buddy!
