That's great Robert, thanks. Mines due to start build this Wednesday. First thing to go will be the std gearknob. I have a number of M10 threaded options, but not a slip-on 😒
On mine once you removed the factory one there was a load of insulating tape covering the original Mazda threaded shaft ,. I can't remember the size but I got a wooden one made for a Mazda and it screwed straight on .
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!
