I'm looking to upgrade calipers and rotors on my 69 bronco. It went through a front disk brake conversion at some point and has an Adelco Moraine 5470 caliper. Will this replace that? What rotors would I need to replace those as well?

Yes, these calipers should fit and replace you current GM conversion. The disc kits use stock 76-77 hub and rotor assemblies and bearings. We would use our part # 3004, though you may find something drilled or slotted elsewhere to look fancier and dissipate heat etc.
