After clearing all the junk out of the trunk, things don’t look too bad! The floor seems pretty solid, but without peeling off all the lining I won’t know for sure. I didn’t want to peel it up yet because I’ll need to do it carefully so I can save the original to use as a pattern. It appears to be a fabric of some kind, backed with a cotton-like insulation. SMS Auto Fabrics sent me a sample of this stuff along with the other interior fabrics/vinyls so It will just be a matter of making patterns from the originals and cutting some new stuff to fit. As far as I know, nobody reproduces the cardboard for the trunk area, so I’ll have to figure something out for that. Maybe glue the reproduction fabric to some hand made cardboard replacements? Maybe spend a few days with a Sharpie and a case of Mountain Dew?
