OK. Here are pics of the original brackets and the repops side by side.
As you can see, I modified the repops so that they will at least be a functional fit.
I didn't worry about the cosmetic aspect. Sandblasted and painted black, no one will ever know once installed because they are pretty burried.
They should work fine.
The pics show the progression of the modification. One odd cut, bend to match the factory brackets, cut and place a small piece of 1/2 by 1/8 steel to fit the void, weld it in and grind the welds down. Normally wouldn't have to grind so much, but having issues with the voltage setting on the welder.
Can only post a few pics at a time, so more pics follow.
