I’m looking for some advice as I’m not a body guy. I ordered replacement floor and trunk pans for my project from Northcoast Musclecar. The question I have is this. The panels have releifs cut in on the edges where they are bent and formed. There are two on the floorpan up front where it connects to the firewall. The slots are about a half inch wide and a few inches long. What is the standard operating procedure for closing these up? Do you hammer and dolly the pieces together and butt weld them? Do you cut a scrap piece of metal to fit the hole and tack it in? or do you just fill the holes with seam sealer. I’m definitely against the seam sealer option as the reason I changed the panel is I DON’T want holes in the floor. Any advice is good advice.
