I ran this on my modified stock shifter for a few years. Ebay unknown brand. Might be the same as the striped ones you see. I have the allen wrench for the three set-screws and had a good experience wrapping the top of the shifter in electrical tape before popping this on and tightening the screws. $20 shipped US should do it. It’s a little bit bigger than the Hurst ball I think.
