Bob,
I have a complete rear sub assy all the way out to the rear rotors, trailing arms, lateral arms. I think most rubber bushings are in place but dry of course.
Also have the rear diff installed in the same assy, unknown condition other than it came out of a running car. I'll sell what you what you need.
I would love to replace the bushings of the whole rear at assy also. Maybe some bushings can be sourced out of all this.
I've not shipped something like this before. It is located in Golden, CO. I can send you pics or attach here.
Scott
