Not more shifter knob talk...
The problem is, I don't have a CNC lathe here. My mill is CNC, my lathe is el manual. I can get one of my friends/colleagues (they tend to be the same

) to turn some knobs, but they would need a bit of a quantity to make it worth their while, and it seems everyone wants something different!
If you can get, say 10 people who are really really interested, I can come up with some programs and renders. Then once I have a material quote and find out how much these will cost to turn and anodize, if we can get ten or close committed, we can go!
If I had my own CNC lathe I'd be all over custom knobs, but this makes it a little difficult.
I might be convinced to make you one set manually Phil, if we can't justify a run... don't worry, I know some tricks so no one would know they aren't CNC'ed.
