I might sound like a knob, but Im having difficulties removing the original stock black gear knob so that I can fit the nice new Isotta one I just bought.

Ive tried everything aside from brute strength to try and twist it off.
Ive got a couple of extra gear knobs and they do have threads through them indicating that the one installed should theoretically screw off.
Can anyone confirm whether or not I need to dismantle the center console to see if there are any screws preventing the original OEM gearknob to screw off?
Any help will be greatly appreciated
