I'm helping a friend rebuild his 95 Roadmaster Wagon. We got to talking, and he really wants to replace the body bushings. Is it all the same bushings as the ones for a sedan? I had a full set a few years back, but ended up selling them when things got tight. He said he can't seem to find them anymore, but I have only looked a few places. If he can't find the stock 9C1 rubber, is there an aftermarket place that makes them? Is Poly to stiff for a southern daily driver? I know some poly bushings have a tendancy to squeak. Is it this way with the body bushings?
