Replacing the focusing screen in a Rolleiflex SL66

My Rolleiflex SL66 kit was extremely cheap given what it included, but not without reason. One factor was the focusing screen, which wasn't a standard photographic screen. I already have experience with the Rick Oleson Brightscreen thanks to my 124G, so I decided to go upgrade to something with great clarity.

Nico has a video covering swapping the screen out, rather than the actual ground glass:
