To make a short story long i was rotating my tires i broke a wheel stud bought a new one and replaced it but when i took the caliper off i took the while thing off. My 2yr old son was "helping" me and i lost one of the bolts. A mounting bolt maybe?? Not sure about the name of it. What i do know is that i used an 18mm socket to take it off. Oh and its an 05 Cobalt SS. Any help would be appreciated

 

Anyone??
