Great video! I replaced the bellows on my mid-60's V8 a few years ago, and the process was exactly the same as you've shown here. About 30 years difference and Deardorff barely changed anything on these cameras. I ordered the bellows from Camera Bellows UK, but they preferred I send the old bellows still attached to the frames, so I didn't have to remove/attach the bellows from the frame. Like you, I noted the location of each screw and the orientation of the frames during disassembly, and everything went back together beautifully.
