No, but I asked this last month. My replies were interesting; cut splines off and weld a stud onto the top of the shifter, use a hair dryer to get factory knob off, thread the splines with a die, drill shift knob of choice and tap threads to install a set screw. I got a lot of replies but none of them seemed practical for what I was willing to do. If you figure something out let us know.
Good luck,
