Well the fenders rotting on a round eye is nothing new. Or a cab corner on any square for that matter. That clean ass frame is a nice gem though. Cleaner than mine which does not have body panel rot like yours. Knock on wood. Patch panels are relatively cheap. It's the time and work to install them and then the bodywork and paint. I'm not sure I'd throw all this metal work at a shop all at once or you may never see this truck again. Other jobs come in, it could end up getting shuffled to dust collector status. Piece it out, test the work.
