Okay, I'm in the process of installing a poly body mount kit on my '90. On the 3 forward mounting locations you have to reuse the factory upper and lower bushing retainers/washers. The problem is that a couple of the upper washers are pretty much rusted beyond use. GM and LMC both carry these, but they come with a rubber bushing already attached and therefore cost around $15........not horrible until you need several of them, and also will rip up and throwaway the rubber bushing as soon as you open them up. Are there any alternatives? I thought of pulling some off a junkyard truck but that's a real PITA considering it's a crapshoot as to whether you will find any in better conditions (rustbelt area).
