Patch Panel Info & pics; "...I bought floor pans from LMC online and cut out whatever I could hammer through after they got here. then I cut nice square panels out of the bad areas, dropped the pans on top, marked them from under, added an inch for lip, cut, crimped, punched and welded them in. do your research... you'll learn what I'm talking about. I haven't done a write up or anything... the rig is a 73 F250 Single cab, not a Bronco..."
