Please feel free to edumacate me because I have yet to find it. I am looking for the yr, make and model this caliper and bracket came from. The bolts are 3/4 hex head and the bracket is mounted on the axle but not welded or bolted there. It slides over the axle and then the bearing is pressed on. The bracket bolts to the axle flange. You can free spin that bracket and the only thing keeping it from sliding off the end of the shaft is that bearing. Caliper is stamped Ford and it is installed a Ford narrowed 9 inch rear end.
