Technical suspension rebuild - lubricant???

Rebuilding the front suspension on the '65 Impala. The factory manual says when putting the sway bar bushings on to lube them with "recommended rubber lubricant".
I cannot find anywhere in the manual what exactly that lube would be? What would a modern equivalent I could use???
thanks-

 

There used to be something called Ru-Glyde. I don't know if it is still available though. Been many years since I seen any.
