       If you don't get an answer here try the two Hallicrafters mailing 
lists.  I think gromets will do fine for replacing the vibration 
isolators on the tuning cap. They also work for the loudspeaker mounting 
in receivers like the S-20R and S-40 series. The originals were probably 
quite soft.
