This is an original pair of 1960's Buick Aluminum 45 Fin Front Brake Drums/Hubs. Pretty good looking condition, but do have some normal wear, some lite surface rust in areas, some pitting in areas and some pitts on the fins in areas-see photos. Brake area measures approx 12"-12 1/16" in diameter-see photos. 5 on 5" bolt pattern. Both are Right hand thread. Not sure of exact years or models these are correct for. Often used for custom projects. Please check my other auctions.
