Love the photos
I'm in the process of completing (29 year process - I don't like to rush into anything) the restoration of a 73 R60/5. Couldn't for the life of me figure out the routing of the wiring harness from mid-frame to the tail lights. Then I saw one of your photos that showed the cable mysteriously emerging from the frame near the tail light - that was the Ah Ha moment. I rushed to the garage and found the two subtle holes in the frame. Don't know why I didn't figure it out myself - too stupid I guess. Photos are excellent! And your restoration is a great read.
