Once I got the CD player in, I needed a place for my CDs. I bought a visor wallet. Unfortunately, once I got a few CDs in there, the visor would sag down when I hit a bump. There being no way to tighten the visor up, I decided to do an end-run around the problem. So I spent way more time than I should have, building this visor support out of sheet aluminum. It has a nylon washer and a self-locking stainless steel hardware. Just flip the tab out, and it holds the visor up.
