Steve… McMaster… The source of all good things mechanical!
This McMaster part looks like an exact fit… McMaster part number: 91145A151 Details below… but first… Vibroplex part numbers…
Vibroplex lists the shoulder washer on their site… Nylon insulator part 8035. Machine drawing shows two shoulder washers with one on the top and one on the bottom? Each 0.25” or less?
Worth asking Steve at Vibroplex? Won’t be the first time a part is listed, but no longer available.
Now the McMaster part number: 91145A151
$13.39/100 plus tax and shipping. Ouch! What to do with 99 extra parts?
I took measurements off a friend’s 1966 Original and compared the McMaster part against the measurements:
I hope some of this helps!

That's it.
Give WWVH man a steak of his choice on me with one of those fancy pineapple drinks with a paper umbrella for the tropical midday deluge.

Those are known as "shoulder washers" or "insulating sleeve washers" and I see McMaster-Carr has a variety. Maybe something will fit...
I notice that Amazon has some too in nylon and fiber...
