Slider knobs ideas?

75slant6 said
So, I’m sure I’m not the only one, but my heater controls in my Duster are missing the knobs on the sliders. Anyone find knobs off something else that works? Or maybe modify/make something that works?
TIA

There is a small set screw on the bottom that holds them on. If you still have them. If not I will check to see if I have a couple.
