B&M shift knobs for A3's vs M6's...
 

I have a Pro Ratchet in my car, for my A3 setup.

I bought a billet shift knob from Jegs, and it barely would fit on there. Why would B&M have two very slightly different thread pitches on those parts?

Billet is cool, but I might try a black leather knob since I have no chrome or billet in my car..
