I am installing my front floor pan in the car. I took the entire floor pan out, including where it was spot welded to the fire wall. The intention was to spot weld the folded-down front edge of the floor pan where the factory one was supposed to be. Problem is I am having a hard time getting the gap closed. There is about a quarter inch gap between the panels with the floor pan pushed up as far as I can get it. What should i do there? I thought about folding the lip back up on the pan so I can lap weld it over the firewall, but i didnt know if that was a good idea. Thanks for the help.
