I am replacing the idler arm on my 71 Duster. On the part of the Idler that connects to the center link there is a rubber bushing/cup. My new moog idler arm came with a foam one (see picture) I still have the original rubber one. Should I use the new one, or just use the old one? The old one seems a much better design, but it may be too loved to be reused? I don't seen any holes that go all the way through the old rubber one, there are some knicks, but nothing that goes through. See pictures below! Thanks!
