right, started with the factory hitch from here:
http://www.rockymountainmc.com/ ($26.00), it already has a 3/4 inch hole drilled in it. you buy the 2 inch square reciever piece and drill a 3/4 inch hole, 2 1/4 inches from the back on both sides. I bought the 3/4 bolt and nut and lock washers at home depot for about $3.00. the reciever piece I got at truck and trailer usa for $20.00.
