There are some rubber suspension bushings that are not available as an acceptable substitute. The ones that go between the Pitman arm/Idler arm and the center link is one that comes to mind, C4ZA-3A196-A. Virginia Classic has one that fits but is not exact. The tie rod end rubber bushings with the metal ring at the bottom are close, you need to remove the "C5ZZ-3332-A" part number that on the rubber to get closer to the factory one. The seal over the ball joints is another problem area and I don't have the original part number, just the replacement - C7OA-3A105-A.
What else?
