Interesting that some one is covering this issue.
Not one of the many aftermarket vendors of ''67/72 parts'' carries the Standard knobs. Only the DeLuxe, with the metal center.

My '68 C/10 Stepside has the all black Standard knobs for Choke, Wipers, and Headlights. I have a '67 K/10 Suburban that also has Standard knobs, all black plastic, but the shape is slightly different. Smaller diameter, and a ridged edge around the circumference.

I run two trucks primarily, a '68 C/10 and a '71 GMC K/1500 Jimmy. The C/10 was a fleet truck. Totally spartan -- no frills.

The Jimmy was built with a Custom trim level, with chrome accents, AC [originally], chrome surround on the windshield, and of course, little chrome [or Stainless] dots on the Dash Knobs. When the original Headlight knob would spin around the shaft, and not turn the dimmer rheostat up or down I was able to buy a new knob, and it works just fine.

When I accidently pulled too hard on the C/10's Wiper knob [thinking it was the Headlight switch -- not taking my eyes off the road] the knob came off. Since I couldn't buy a new Black Standard Knob, and didn't want to replace all three, I had to fix the old knob.
I packed baking soda down into the web spaces around the D-Hole the Wiper Switch is machined for, and sealed it with Superglue. The combination of sodium bicarbonate and cyano-acrylates reacts very fast and dries hard. The fix worked.

I may try more cyano-acrylate glue on my OEM DeLuxe Headlight Knob, to stop its spinning. If I'd thought about it earlier, I could have saved about $7. I can still fix it and have a spare, I guess.

Having a spare Headlight knob [and shaft] is handy if you want to energize the electric harness [for test purposes] when the Instrument Panel is off. Without it, and the Battery connected, the Headlights are at comstant ON. Only disconnecting them under the hood, or pulling the Batt cable will shut them off.
Unless you use the Knob.
You will have to remove it before putting the dash panel and ferrules back on, anyway. But it's good to have control.
