Check with Daniel at Ricambi -- he's usually got them. In fact, he shows it here:

I prefer the chrome ones unless you insist on original. I found my original too small. The 47mm would work fine unless you have really big hands.

You'll have to check out Branko's gear shift knob when you come down on Saturday. He customized his own for his Euro 308.

 

Mine too... it's custom made in carbon fiber. The sphere is slightly larger than stock... fits better in the hand.
