Had a power steering leak that ate away the driver side front shock lower bushing. I can't tell if they are Explorer 1,3,or 9000's (got it used). Anyway it clunks around and just wanted to know if they are Jeep parts or Pro-Comp parts, and if the latter can I just get the bushings without buying a new shock? I don't need anything fancy since I'm not going to be changing out the rest of the bushings anytime soon. Thanks for the help.
