Aftermarket control knobs for G&L L2500?

I am considering replacing my control knobs on my American G&L L2500.

There is nothing wrong with the ones on there, I know they are good quality, but I was thinking of getting black ones.

I know the L2500 has solid-shaft potentiometers, so I want to make sure there are knobs out there that will fit it before I purchase.

Does anyone have recommendations?

Thanks.

 

Thanks for the helpful sites!

This is the dimensions of the bass according to G&L’s website:
20mm Diameter x 19mm Height (0.78" Diameter x 0.75" Height)

 

Sorry I meant to say it was dimensions of the bass's stock knob according to the website.
