Twin Jimmys - yes I overlapped the patch panel onto the original a little rather than using a butt joint but what you are seeing is actually weld through primer on the inner to outer patch panel.
klhansen, I plan to screw the driver's side together similar to what I did on the passenger side and fit check the door before doing any welding. I was really surprised how much the driver's side post could move compared to the lassenger side.
