Hearing how they fiberglassed over the rusty floor brings back so many memories of how some "repairs" were done in the old days. I've seen plywood screwed over rusty floors, then tarred over, rags and newspaper shoved into rusted out body panels and bondo'd over, and chicken wire and fiberglass cloth used to make new body panels !

When I lived in Pennsylvania the cars had to pass State inspection 2 times a year and there cold be no visable holes in the body or frame from rust. But all you had to do was shove some rags or newspaper in there, put a layer of bondo over it, spray it with some paint, and you were good to go. I've bought cars where the frame was almost completely gone from rust, but the bondo routine made it pass inspection.

You are doing a really nice job on the old Plymouth. Those repairs will make it so much better.
