I'm looking to replace the worn bushings on my '66.
It appears there are three choices:
1. Original rubber
2. Polygraphite
3. Midolyne
Anybody know the advantages/disadvantages of each?

My understanding is polyurethane offers the best support but has the tendency to squeak,and transmit alot more shock and vibration thru the chassis. Polygraphite is similar but with graphite impregnated into the poly to resist squeaks. Although Ive never seen midolyne Im told its stiffness falls between rubber and poly with no noise issues.
