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.
