I don’t know how to cast something hollow. Anyway, my goal is to come up with something cheap and easy. Can you suggest phrases to search for? “Shock mount” and “vibration isolator” mostly pick up mike stands and heavy automotive/HVAC stuff.
The shape is a hollow ball with a flange at each end and a hole through the axis. You squeeze the flanges through the mounting holes in the chassis. With 348-007 (used in Type D and H from the 1950s, now deteriorating) you finish up with screw-washers-nut through the hole to prevent a big shock from tearing the cushion apart. 348-0087 (used in Type 1A6 and 1A7 from the 1960s and may outlive me) is a different material, stiffer, and instead of a screw, it is secured with a plug at each end. I think 348-0087 would fit in a D or H.
If I had access to the PISL (Purchased Item Source List microfilm “window cards”), I could determine who Tek bought them from - if they bought them - but they’re surely gone now anyway.

Could you make a mold and cast some sort of rubber?

I performed this procedure on one of the chassis cushion mounts in my Type D plugin. (Tek P/N 348-0007-00. 348-0087-00 might work too.)
