I have been making and using these cups since 2011 to mount all sorts of things to various bolt holes on cars and vehicles. The uses are endless and have allowed me to build clean mounts for tube steel bumpers, chassis braces, strut bars, rock sliders, swing out tire carriers, and more. The bore is designed to fit virtually any oem bolt on vehicles and has a 1/2" through hole that can easily be opened up to accept any shank size bolt.
-Sold as a pack of 3
-All dimensions +/- 0.01" Please let me know if you need more precision and I can easily accommodate you.
