Scott Harms is a distributor as well. Good Moparts member! Also, you can reduce trimming and fitting time a bit by using a rubber mallet to gently massage the floor down to close up some of the gaps between the connector and the floor. Don't get carried away or be lazy, but it does help with closing some of the gaps before welding. I welded two sets in so far from under the car and had to use reverse polarity and a stich weld technique to get a nice bead and keep the heat in control. I used a 50-year, paintable, black roof caulk to seal the entire weld, make it look pretty and seal it up prior to undercoating the area with Resto Rick's undercoating and a Shultz gun. It looks factory to the untrained person.
