If you're willing to head north a few hours, there's Carlos Leon in Palm Bay. He was on the cam weld list and he did mine, as well as a few other things afterward. I can pm you the place where I last knew he worked (it was a dealership, not Ford). He owned a 99 I believe, though he may not have it anymore. Don't think he ever had a gen 1 or 2. Beyond this, I can tell you the name of a shop that did my transmission. They got my business since they claimed to have done another gen 3 before mine.
