The primary use for the SS-184 stainless steel mount is for antenna installation on 1994 - 2004 style Dodge Ram and Dakota pick-ups, They will not fit 2005 and newer vehicles, When the hood is open, the fender bolt near the firewall is removed (right or left side) and later reused to bolt the antenna bracket to the under-hood fender lip, All mounting hardware is invisible unless the hood is open, Additional stainless steel sheet metal screws are supplied if additional strength is determined to be needed, The bracket has a pre-determined bend and does not interfere with the closing of the hood, The bracket is 2"" (51mm) wide by 4, 1"" (104mm) long, Due to the close quarters, the stud requires crimp-on coaxial connectors, SKU: CBDST3106
