I have had urethane bushings in my B-body cars over the years and the reason was two fold. First I thought it would improve handling and secondly was because they were supposed to last much much longer. They aren't supposed tp be susceptible to the elements and age. I never noticed any adverse affects to ride comfort ( the Chargers and Roadrunner were never meant to ride like a 300 anyway ) but I can say that the bushings must be properly lubricated during installation or they will squeek incessantly and drive one nuts ! Can someone with a parts book determine interchangeability and then perhaps we can go to Just Suspension or PST and say "hey.. we've got X number or people willing to purchase... how much to make 'em? " Wasn't this done with a special tire size the group needed a couple years ago? With 3 '64's in the family, I for one would purchase a few sets... just make sure they mold 'em in black and not yellow, red etc. Mike Laiserin [Non-text portions of this message have been removed] To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm Yahoo!
