The employees at aerostream have gone above and beyond to make sure that this do it yourself kit was not only all correct and easy for me to install myself, they also followed up with me, faster than I could ask for help. Then when I decided to add more height to the existing risers, I went to menards and they didn't know much on how to answer my questions so we fudged through the ordering process and before I even got home the customer service reps at aerostream had called me to clarify what I was trying to do and to make sure that I had the correct parts, best customer service I have seen in a long time, thanks again for the help and advice, Chris
