Hey Felix, welcome back. To install the Curt 7-Way RV-Style Trailer Connector item # C58155, you'll want to use four .19" diameter x 1" long bolts and nuts. This will secure it to the Curt Mounting Bracket item # C67UR, you purchased.
I recommend using some Loctite Threadlocker 242 item # LT37418 when you bolt the 7-way to the bracket.
