Yes, I've been thinking about reducing the amount of shiny stuff on the boss.
I'd love to cut down the gear lever...as would Aldermog. But it widens right out to double it's diameter immediately below the gear knob fixing collar so you'd never get a knob on. The only option would be to turn the whole thing down in a lathe or construct a new lever.
The later Mazda boxes have a nice delicate lever.
