I ordered rear strut mounts with my new struts. The Lexus parts store had a specific left mount and right mount. The struts were interchangeable.
I received the mounts today and I see no difference between the mounts. The part numbers are different on each mount like the order, so no mistake was made with the wrong part. I was expecting a bolt pattern difference but they look identical to me. Can someone explain what the difference is supposed to be.
