I have my floorbards cut out pretty much from the seat forward and a friend will be helping me replacce them next weekend. I have replacements recieved from classic parts and my problem is that my friend has suggested screwing the floorboards in place. I have a fluxcore mig welder but have found welding sheetmetal is hard especially with someone with no welding skill. Is there another safe way to replace floorboards without welding.
