I remember some recent dialogs on shifter wood knobs recommendations. Figured I would plug in a great company I recently worked with to get a knob to match my new Lempert Nardi flat steering wheel.
Gary at C&G Woodcraft does amazing work, his custom shift knobs are solid, and has these in various types of woods/finish/thread sizing--- 7/8/10/12mm.
He has an ebay store-- cgwoodcraft .. Check him out if you are shopping for a knob. Call or email him if you have any Qs... Incredible customer support and product.
Enclosed are some side by sides of his porsche knob and my current stoddard stock knob.
