I am a professional technician by trade. I've mainly worked on GM vehicles, specializing in Corvettes. Ordered a set of front upper ball joints. When they arrived they contained nothing but AC Delco parts. They were cheap offshore, no brand fit in a General Motors AC Delco box. Those ball joints get a full deduction! on the judge's field. I also doubt the quality if they are to be ridden. Do yourself a favor and go to your local auto parts store and buy from there so you can check the quality of the packaging.
