NEW Buick style, 45 fin brake drums. They come unpainted and unpolished, and have a 5 x 5-1/2" bolt pattern. The center and braking surface is cast iron, and the outer ring is cast aluminum. These work with our reproduction 1940 Ford style hubs and all of our Lincoln backing plate/brake kits with 2" shoes.
15x5 pickup steel wheels will need at least a 1/4" spacer.
On aftermarket steel wheels a maximum of 3 ¼ backspace can be used.
