I will have to pull the NL2 knob from my 1972 Cheyenne and see if it is the same dimension as the wiper knob. It might be the same as the manual throttle control knob 1991067/1991072, which was a deeper knob also retained with a set screw. The manual choke or Suburban rear air knob 1991077 does not have a set screw for attachment.

Manual throttle knob:

It appears that the knob is or is similar to the throttle knob based upon this pic

Here is another photo of a true NL2 knob:
