Stacked plastic jazz bass knob

[PrimusPanda]

Has anyone seen the black, plastic jazz bass knobs that are stacked for a concentric pot? I remember seeing them a long time ago but haven't been able to locate them again. I am putting a concentric pot into my Jaguar because I do not want to have to drill a new hole but I prefer the look of the plastic jazz knobs over the P bass style knobs. Anyone remember seeing these or know a trustworthy site to get these from?
