Even taking the tail light out, I still have that inner panel in the way and not sure what I could get in there to pop anything out. I could of course jam something between the inner panel and dent and pry on it but, then I risk jacking up the inner panel.
Anything else besides a slide hammer and $400 stud welder? Any clever home brew stuff out there? Weld a piece of metal to the center, attach chain and pull out with my van?
