I’m splicing in a replacement Driver Side Uniside Piece . On the top of the cab the pieces meet up nicely , but on the bottom or rocker panel the ends dont meet up . The new piece is about 1/2 inch higher than the piece still attached to the truck frame. My question is this: Do you pull the two pieces together and hold them there and weld, or do you get them to naturally align up and withouth having to be held in place then weld them. Any help form you experts out there would be appreciated
