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.
