I have a 73 f-350 with a dump. I pulled up the rubber that was on the floor and found my floor boards all rusted out. I can see to the ground in a couple spots. I know now that I need to get new weater stripping for the truck. My Question is what can I do about this? Is there floor board kits you can buy? Cut out old floor board and weld in new floor board? Patch it up? Any advice would be appreciated.
