Where can I find these knobs?

[Last Triumph]

I'm looking to fit some CTS pots which have what I believe is the USA type 24 spline (fine) split shaft as per below....

And I'm trying to find some black push on knobs like these.... (or similar)

Pretty simple, huh?

Not from where I'm sitting - all the push on ones I can find have the import 18 spline coarse split shaft, or the screw on type with the little grub screw which is no use for those split posts.

Where can I get these knobs WITHOUT the grub screw type fitment - I want the correct push on 24 spline knobs.

Any clues?

You can use set screw knobs on a split shaft pot, just make sure that the set screw aligns with the slot. That way the screw pushes out on the split halves making for a tight fit. If the set screw goes into the splines it will just crush the halves together making for a sloppy fit and possibly a broken shaft. If you have a knob for the larger solid shaft pots, then brass bushings are available that slide over the shaft to make for a tight fit.
