I would not go to the trouble of drilling out a bunch of spot welds to hammer and dolly. If it could come out easily that would be one thing, but that is a lot of work.... Trust me on that one. The stud guns from HB are ok, but the actual puller kinda sucks. Purchase a decent one and save yourself the headache and trouble of drilling out all those spot welds and then trying to get it back in correctly.
