Any tricks to working under ‘71 Duster dashboard?

J par’s picture of wiring reminds me of what it looks like under my hood. The squirrels have destroyed my engine wiring at least twice. My days of being young and flexible while working upside down are not easy as they used to be..... I bought this ‘71 new when I was 19. Me and the Duster are showing our years.
The opportunity arise when I took the windshield out to be replaced. At that point it was just the five screws at the top of the dash thunderbolt on either side and out it came..
