Everything was great. The two Plastic clips that hold the support rods to the bed rail were broken. I will email the place where I purchased it. Other than that This is a Great Quality bed cover! Very easy to install! I will recommend this to all my friends.

The 3 rubber spacers were not needed for the side rails. When they were installed it made it impossible to clamp the side rails down flat. Removed the rubber spacers and they installed beautifully. Loved the way Undercover cut out the side rail for the grab handle on the GMC multi function tailgate. Side rail fit perfectly.
