I often use silicon fuel tubings as used for miniature (1:8) petrol racing cars. Make sure the inner diameter is small enough to give a tight fit and use length of 1 - 1.5", so it won't slip. Wall thickness is often .1", which is a good thing.
Alternatively, many 7000-series plug-in modules contain the same couplers and parts units can be had for pennies.

Those fragile plastic flex connectors are impossible to find as far as I know, but I question whether a flex coupler is even needed there. The VAR shaft from the knob back to that flex connector is a piece of 1/8" fiberglass rod which I imagine takes care of the insulation out to the knob, so maybe a normal aluminum connector would be just fine. The fiberglass rod should take care of any misalignment too.
The last 1/8" shaft connectors I bought were from Veronia Northern but I'm sure you can get them from others.

These are those connectors with two set screws, that look like a piece of thick wall aluminum tubing.

Just picked up a 466 over the weekend. Works fine, but the only
problem was the Var knob on CH 2 is broken. Opened it up and saw it
was the coupler that connects the two shafts that's broken. Is there
a source for the couplers? I might just leave it alone as it looks
like a real pain to get down to the Ch 2 stuff.
Thanks,
