Me too, with a Zinc washer and Neoprene washer (on the outside), lock washer and nut on the inside.
I installed them with the bolts facing up and had wifey tighten them from inside the cab which I held with a spanner below.
I used 5/16 bolts (1/2" heads) by ~2.5" long.
I can post a pic from below if you'd like too.
