I have some 2" wood balls left from another project. After living with the stock metal knob, its rough edges and hot/cold, I decided to try to make my own. I have a black Alcantara/red stitch interior, so I made a red stain for the shift knob. The threaded insert came from a kit that includes a drill bit, tap, insert tool and 10 threadcerts. A search listed many sources for wood balls if you want to try making one. I used the dimensions that B r i a n posted on this thread. I have enough parts left to make four more if anyone is interested.
