Oh, Also I have a design for a shift lever extension made from 6061 Aluminum. It is 1" in diameter, and raises the knob height by approximately 2"
It screws directly onto the lever and is adaptable for pretty much any shift knob that has a hole deeper than the 1.5" tall threaded shaft.
Here are pics with a custom-made sphere shift knob made to blend smoothly with the extension.
This is a special order item which will be made for a customer who is definite about a purchase. It can be made with an aluminum or copolymer knob to fit directly with it as well. Its all up to you.
