What I did was, cut the outer radius off the outer house....
The middle of the outer house is still in tact...
At the top center, just before the house starts the bend tward the quarter
I cut there, from the front to the back....then I cut the lip 1/4" back from
outside of quarter, that not only cleans up the lip but cuts the factory spot welds free. Once the old stuff is out I took some thick construction paper and made a template...once that fit good then I made it out of metal.
I've got some better pics of the mod I'll have to post tomarrow...
that was the best pic I had on hand...sorry
The middle seem is were the DSE tub meets the out house.
