It's been awhile since I have made any progress on this, but I found some time to work on it this weekend. I got both quarters, roof, and tail panel off. Here are some pics.
I got some more done over the past several weeks. The passenger quarter is prepped and fitted, I used this stuff called rust bullet on all the metal surfaces, I started to cut out and fit the trunk floor, passenger drip rail is mounted, and the flanges for the roof are ready to go. It's starting to look like a car again
