ALLRIGHT !!!! Let's get into some repair !!!!!
The Rocker was pitted badly at the rear section and also under the lower corner of the door jamb. So if I was cutting it this far apart, I might as well include that section as well. Plus it's easier to align the longer piece when installing. In this photo I had not yet cut out the lower half of the original.
Close up better shows how bad this was, particularly the front edge along the 1/4 panel to Rocker seam. It would have been impossible to spot weld repair that.
Of course the replacement panel is not exactly the same size.
Here you can see an early mock up where I had already slit the front face of the panel. It had to be sectioned to shorten the face to the exact width.
Top half mocked in. Doesn't show in the picture but the wheel opening end was also reworked to replicate the original folds.
Here's the bottom half. Note the weld line, the lower face was also too wide and had to be sliced and cut down ! The cross section of the replacement panel would have nested over the original section... Way Off! The wheel opening end was also reworked.
