This is an original pair of 1951-52 Ford Truck F2 F3 Front Brake Drums/Hubs.  Pretty good condition, some normal wear, some lite pitting in areas, threads look useable-see photos.  Brake surface area measures approx 12" in diameter, and approx 2 7/16" wide.  Both will need to be turned-see photos.  8 Lug, 8 on 6 1/2" bolt pattern.  These are correct for '51-52 Ford F-2 and F-3 Trucks (2wd) and '51-52 Mercury M-2 and M-3 Trucks.  Would also fit '48-50 Ford/Merc F2, F3 Trucks, but you would need the '51-52 Style backing plate assemblies with the wider brake shoes.  Please check my other auctions.
