well i just did a number on my 68

How about getting a stud welder for cheap at HF and watch a few you tube vids on how to use it? You just grind off paint, put a **** ton of studs on it and take your time with the slide hammer. Its really not as hard as you think. Once you get started and slowly start pulling that out you will be amazed at how close you can get the panel. Use a lot of studs. porcupine style. Nice gentle pulls, dont try too hard. get the car up to working height and get comfortable. Do 20 min at a time. If it is going to the body shop you might as well get some practice. $0.02
