Cab and Core Support Mount Bushings

[aotte1]

Body mount bushings to use in restoring 64-66' cab and core support?

For polyurethane thinking of "Energy graphite" , as they adjust hardness for each use.

For rubber thinking I read about vender here on forum that has new ones of quality. Maybe located in the west? Their description sounded like quality parts.
Anybody know their name?

Search on forum provided lots of complaints about polyurethane squeaks when driving. Not sure if just for front control arms, or includes body bushings too?

Do polyurathane bushing put to much stress on the cab, thinking 50 plus year old cab and do not want to put cracks in it?

Kind of leaning towards new rubber if good quality ones are available, nor junk imports.

Going to use US made rubber cushions, sold by Classic Heartbeat. Using the 67-68 version. They are a close fitment to the 64-66 ones. Many of the parts are the same. Will report back on how they fit and any differences.
