i dont see what the problem could be with changing the gear knobs around. I was thinking about aquiring one for my XF auto. I have already replaced my XF tacky-plastic-with-orange-button gear knob with a nicer EB grey-rubber-with-black-button gear knob. As far as i know most auto gear knobs use a universal thread so you could probably put whatever you wanted on it. I was thinking about putting a VT/VX Commodore or current model Magna gear knob on my XF (you know, the ones with the button on top, not on the side) but then when i saw the BA gear knob, i decided to wait til i could get one of them.
