The beltline on the back of my cab is rusted out in several places. These cabs were built in multiple pieces and each has a "c" shape overlap that becomes the beltline. The roof piece overlaps on top of the back piece of the cab.

When I patch the cab does it still need to be two overlapping pieces so it can flex or move? Why can't I fabricate a beltline bump and weld in as a one piece repair?

Clear as mud? Thanks!!
