My 52 - 210 has holes in the front floor pan. I have purchased two new units. One for the driver side and one for the passenger side. It looks like the floor pan comes apart in about 6 pieces. Are they just spot welded in the overlay areas and then leaded to close the gaps? If so, can I use a cold chisel to open and remove each section? Any ideas? If I can get each front pan out, I hope to have a shop repair them with the panels that I purchased. Thanks for the help.
