There shouldn't be any factory bolts on the vehicle when installing Curt trailer hitch # 13591. The hitch comes with the six M12-1.75 x 40mm bolts needed for installation (some installations only require 4 of the hex bolts). I have included a link to the installation instructions for you and a video showing an example installation.
