I've got a 91 with 6" front tuff country springs. I somehow managed to bust a poly bushing. I have a couple new ones laying around with different dimentions, and can't seem to remember if these are for my front springs or not.... one is a 60310 and is about 1.52" and the other is a M02270 and is about 1.56" (i think this is the metric ones for the rear?) I want to find out before i take it apart and see.
