new to site and (go figure) body alignment problems

[sawyer]

This site is great. Just reading through the previous threads has helped out quite a bit, made me feel a lot better in dumping 9 grand into a rusty 72. These things are addicting. One thing that I read about was shimming the body mounts to adjust the alignment on the doors. I'm not quite sure how this works and any information would be a huge help, as there are some serious gaps b/t the window and the frame. I'll try to post some pics, it comes home from the paint shop in a couple of days.
