Lawrence,
Sierra Madre used to have them in black, but I can't find them on their website now - so try calling them.
Maybe also try calling Tom Gould at TC's Garage in San Marcos to see if he has them or can get them (they show a 68 911E Targa, so has a line on the early 911 parts from their resto.
AA had them too, & pre-Eklers Automotion/Performance Products carried them too (didn't look..
However, they're at Lakwell.com in Belgium at the link below - ignore that they call them heater lever knob (those are red):

If all else fails, the VWs used the same black knobs, so maybe ISP or some of the other SoCal Dubbers shops have them in black.
Tom
