Want it to handle like a new car!!!

If you go back through the back issues of the Mopar mags (don't recall whether it was Mopar Muscle or Mopar Action) from earlier this year there was an article where they put the Hotchkiss kit on a B-body and tested the handling at each step.

The Hotchkiss stuff is not cheap but it can be done in stages or by reading the article you could likely do similar things with parts from other manufacturers or make them your self for considerably less.

FWIW, my 68 Barracuda had a recently rebuilt front suspension with rubber bushings. When I did the 73+ disk brake swap I rebuilt the doner car suspension pieces with polygraphite bushings. I did not notice any improvement with the polygraphite bushings and did not notice any degradation in the ride quality either. But within a couple of months the poly strut rod bushings started to squeak (I did use the special grease provided with the kit). It was bad enough that it was embarassing to drive into a cruise night with the car. You could make it stop for a week or so by spraying lub on the bushings but it would come back. I finally took the front end apart again and went back to Moog rubber bushings. The shackle bushings are poly grahite too but they went about three years before starting to squeak, they are easy enough to remove and regrease that I did and its been fine since last spring.

If you are going to make a track car the poly bushings are probally a good thing but I don't think they are needed for a excellent handling street car and you won't have to contend with the squeaking.

I would venture a guess that the majority of folks that report a dramatic improvement with poly bushings are going from a worn out rubber bushing front end and those that haven't had squeaking issues likely don't drive 6-7k miles a year.
