I took it to several body shops and got a bunch of "No-Bids". One place had a sub they called "The Maestro" who was incapacitated due to recent surgery, they said he was the only guy they knew of who could touch that kind of work. It seems most places just want to bolt a new, factory fender on. Of course on our 25 year old rigs, those are made of unobtanium, and used ones are typically rotted out pretty badly. So I decided to tackle it myself.
The first step would be to cut out the mangled section. I drilled out the spot welds on the pinch lip at the bottom, and used a cutting wheel on the rest. Here is what it looked like after I had sand blasted all the edges, the inside and outside, and put a coat of zinc primer on the bare metal.
