Here's a shot as I was getting the '72's bedsides removed. You can see that the inside of the bedside is beat up....I found that I could break the spot-welds pretty easily by using a BFH. Made a long chore much more tolerable:

...and here's a shot of the finished product, after MANY hours of work:

I then got started disassembly of the '67 bed. This is going to take quite a bit longer, as I have to be much more careful not to mess up the side panels...and many of the spotwelds are very difficult to get too. I decided to use the air chisel and remove the bed floor, leaving a little bit of metal around the perimeter. Then I can go back and carefully drill out the spotwelds and remove the excess. By the time this is completed I'm actually going to have quite a few man-hours invested into this box.
I have a bunch more pictures, but I'm tired, dirty and hungry, so I'm going to hit the showers and then get a bite to eat. I'll probably go ahead and post a project update page tomorrow evening with the additional pictures.
