Henry J shift knob. I made one of these as a gift for a buddy of mine so I figured I'd make an extra one while I was at it. Medallion and all hardware is solid brass. Comes with one solid brass adapter to fit your shifter in your choice of the following thread sizes: 5/16-18, 5/16-24, 3/8-16, and 3/8-24. If you need a different size, I can point you in the right direction. If you have any questions, please ask. Thank you! $85/shipped in continental US. A few bucks more will send it overseas.
