It looks like we sold our last Yakima Bolt Upgrade Kit 8860007 in August of 2015 and there is not a replacement from Yakima. It does appear the kit includes four 1-3/4" hex key bolts and a hex key. You will likely be able to find these bolts locally from a local hardware store. Unfortunately they do not give a measurement on the bolt diameter or thread pitch so be sure to take the bolts you are replacing with you to match the diameter and thread pitch with the new bolts.
