Thats nothing.. i have one here we are doing major repair too.. a stud puller and a slide hammer is all that is needed for thoughs. Unfurtuantely you can't get at the outter sheet metal from the inside to use dolly and hammers. If it goes for the body work with paint and blend.. expect into the 3000 range to fix it and they will probably want to remove the box to paint the whole back of the cab and blend onto both rear doors and rear window needs to come out. So 95% of the time you would be looking at new box bolts and clips as well.
