Great thanks for the info. That's the reason I asked, I was trying to buy a gearknob so I could fit it at the factory. I was told the shaft had an M10 thread, which is the standard Mazda gear lever. However, I then heard of gearknobs coming loose and being held in place just by a grub screw. So I wondered if the shaft was actually threaded and it appears it is. I now have a collection of five gearknobs, bakelite, aluminium and wood. Some threaded, some slip-on, so hopefully one will suit!
