going to replace the body bushings on the 67. this is a street/strip car (its going to shake anyway). whats the best way to go? are there advantages to either? and if poly urathane or graphite? thanks Dave

We put poly bushings in my sons' Chev truck and after a few months of heavy off road use the cab cracked above the rear mounts. I was able to get a piece of angle iron up in there to brace it so it's ok now. My point is if there is going to be alot of flexing go with rubber. Do you drive on dirt roads? Very hilly? Big driveway dip? Convertible? Go with rubber...I say, stiffen the frame not the mounts.
