I recently purchased one of these fine shift knobs from WC Lathe Werks, used it for about one day and I quickly realized that I needed a larger ball and shank. Story of my life...

So, I talked to Chris @ WC and he is making me a custom deal. Super nice guy to talk to also.

So my loss, your gain. WRX Copolymer Sphere w/ brass insert. $89 new, or $80 shipped in the US for mine.

Website info: 5MT Copolymer WRX Sphere

I can get pics, but it's the same thing as from the site and it is mint. The weight is great and the beauty part is it doesn't get cold in the winter like a metal shift knob!
