I removed one of my tack welds and managed to fit the bracket between the hinge cover pocket and the bottom plenum cover. Not a perfect fit as it appears to attach to the bottom of the step flange. It would take major surgery to raise the step flange side as the top of the support bracket is touching the inside of the hinge pocket. I bet im not making any sense.
I guess it might not matter as the fender mount hole is huge. Tolerances appear generous. The top of the hole is within 1/16” of the original vertically.
