I'm getting ready to re-do the dash in my car (new switches, bulbs and painting it) and my headlamp and wiper switch knobs are looking bad....cracking and peeling. I'm going to attempt replacing them with some billet knobs that are sort of for street rods I guess. Here's what they look like. I should have them in about a week.
i think they would go good with the cranks in this thread http://mmb.maverick.to/showthread.php?t=86650&highlight=billet
I received the knobs today and slipped the wiper knob on. Nice fit and the set screw will hold it in place well.
