Squarebody Shift knob options

[ShortHaul]

I've been looking to upgrade my stock shift knob on my 75 C20. The plain old rubber knob is not that interesting, and mine is loose and slipping off the lever so I figured it'd be a good time to swap it out... Thing is, the lever is not threaded, like 99% of all shift levers in the known universe, its splined...

There are a million cool options for shift knobs out there, #14 billiards ball (green and white to match exterior, wood to match woodgrain interior, cool marbled epoxy or glass etc etc etc, but they all have threads instead of splines...

I'm wondering if anyone knows of a spline to thread adapter that could slip on the splines, but provide a threaded exterior to accept a threaded knob? I've done lots of googling, but no luck so far. Also have searched far n wide on this site and found nothing.

With all the cool custom squares out there I can't imagine I'm the first guy to want to ditch the boring rubber knob for something cool!?
