Glen,
I have a 4t6 that had metal floor pans that were shot. I'm not sure how similiar the floors are but the principal the same. I made a template and laid out some sheet metal and made my own with limited tools. I'm sure you could or take the template to a sheet metal shop and have them make for you. Maybe your wood floors could be used for templates or good enough to be covered in fiberglas and used. Just a thought. Some pictures of my floor here. May or may not help. Have fun and good luck
