[TR] Rubber bushings

[Mike Denman]

Hi group,
    A question if I may... Rubber bushings like those used on the upper 
fulcrum for the TR3 a-arms... the rubber bushings ride on a machined bare 
metal shaft (fulcrum). I ended up replacing the original metal fulcrum 
because over the years the metal under the rubber bushings was really eaten 
away by rust. So, with new fulcrums installed, I would like to avoid the 
problem of rust starting under the rubber bushings. Normally I would use 
some grease to hold the rust at bay but grease (at least general purpose 
grease) will cause or hasten the deterioration of rubber products. Any 
advice on what to use and what has worked for other members would be 
appreciated.
