I just had the Body Kit installed a month ago and I needed to order the installation kit myself. I am reading that part number directly from my service invoice for the installation. There were only 2 of these rivets (51-71-8-219-511) in the kit, the rest of the kit included the the jig (01-29-0-402-662), and 25 other rivets (51-71-7-002-953) that hold the front of the flare which extends off of the running boards.

I posted the PDF instructions for the installation in another thread that's running here for you.....
