When I did my own car, I spent about $400 on parts here on PP, and did the labor myself. I did not replace the guide rod mounts, as they were still stiff and no play was found in them. If you are a DIY kind of guy, you can do all the work yourself. If not so much, then you can do as much as you are capable of, and farm out the rest. You will definitely need to have the alignment done by a professional. If you are near So. Cal, I could maybe help you out...Rich
