i've been using a piece of 2x4 along with the hammer, not doing so well,
and the holes are pretty far spaced apart , and dont think they'd pull it much.
i've been brainstorming picking up a come-along , drilling a hole in the center of the damage, and through a 2x4 placed behind the damage, rig up some sort of bolt through the 2x4, sticking out the body, connecting to the come along, which is secured to a tree maybe, and pulling it?
anybody ever done something sim?
another problem is having all the seat hardware in the way.
save yourself some money and put some armor on there, like gen right sliders. take out the seats and beet them with a BFH, get them to the right depth, then throw those rock sliders on there, and never look back..
You may want to take it to a body shop that has a stud welder, puller. It's a tool that welds little tabs to the body which then can be pulled on with a dent puller and get the major dent out, shouldn't cost more than a few hundred. Then finish with a hammer and dolly.
If you don't want to do that then get a good hammer and dolly set and with the dent pick(looks like a sharped ball peen) wail away at the dent making a bunch of little dents, which will start to push the panel back into shape. It is going to look bad at first but keep working at it with hammers and dollies and it will come back, I've fixed much worse. Or you can bolt some angle iron like 3" x12" or so to the seat mount and use a bottle jack with a large piece of plate steel and force the panel back. Good luck!
Pull the seat bang the dint out without the 2X4, if anything use the 2X4 on the outside to bang it flat. Go easy on it but it shouldn't be too hard to tap it back in from the outside if you go too far.
