For what ever it is worth, I found a small shaft coupler from McMaster Carr for around $25.  It has a urethane element which will remain flexible for many years.  (I kept the original for a later rebuild, if I choose to do so at a later date. ) This was on my 37-116 (code 122).

I also purchased a repop dial from Radio Daze. My originals were damaged beyond salvaging.  The quality and look are excellent. I am very pleased with it! Looks original, only slightly thicker material. It shouldn't be quite as fragile as the original, while still maintaining the same color and translucency as the original.

Good luck with your project.
