Where exactly do I sand the mount at. The two bolts that hold it to the tire carrier, or where the attenna attaces to it? Fawk me I ordered the firestick coax shit, and fogot to order a stud. To top it off, I think the hole in the teraflex antenna mount is too big, and may need a bushing for my fierstick antenna to work/ Help! I know I need a special stud to accomidate the fire wire coax thing, but do I need a bushing for the teraflex mount, or what>?
