Originally I received two lower arms instead of one of each. Paul from Florida got two uppers. So we cross shipped them and now we each have a complete set. I also got a restraining bolt in the process. Paul had an extra one and gave me a very good deal on it.
Side note. These arms are a lot smaller than I thought they would be. But man that restraining bolt is way bigger than I thought it would be. I have it on the fridge right now.
