B&M ''Pro Stick'' shifter ball replacement question

[toofastforyou]

My son has a B&M ''Pro Stick'' shifter in his T-Type which has a white ball on it with the B&M logo. The white sticks out too much in the car and I was wondering if someone makes a replacement black ball, or even better, one with the ''power 6'' logo on it that would fit that shifter?
I remember about someone who made a black aluminium ( ? ) ball with the ''power 6'' logo on it but I can't seem to remember who that was...

thanks,

Claude.
