[Hallicrafters] coupling

[Jack Schrader]

Not  really hallicrafters but at least it is ham radio related.

After taking apart my Viking Valiant I found a problem. The insulated coupling that connects the vfo tuning knob shaft and the tuning mechanism behind it is broken. Where can I get one of these couplings that has an insulating wafer between the front and back half.

The input shaft has a diameter of 0.25" and the rear half has a diameter of approx. 0.189" and it has a width of 0.645" approx.

Thanks in advance for your help!
