I didn't want to drill a bunch of holes and use a slide hammer to take out the deep dents and creases on the back corners so I decided to heat the metal and stretch it back into shape. I didn't have any long body tools to reach through the tail light holes so I went to the the throw away tool store, Harbor Freight. I bought a couple long screwdrivers, heated them up and bent them to reach where I couldn't get to.
