These studs and nuts are used to repair the passenger side mounting studs. The studs need to be drilled out using a 1/4" drill bit. Once done, use a 2 part epoxy and install the stud. Make sure to avoid getting epoxy on the threads where the nut will be installed. Once dry, install the bezel into the dash and use a 3/8 # deep well socket to install the nut. CAUTION: Only tighten finger tight to avoid cracking or breaking the bezel.
