Trouble is the narrow shoes. Most people change the backing plates (that requires the rearend to be town down) because the new axles are slightly longer so they can use commonly found brake parts. If you search the right drums are around used and I see new ones ocassionally. There was a guy on this site that had 6 new made in USA rear brake drums and if I recall correctly had only sold 2 but I can't find the thread. There are good used ones on the site from the guys that change over to BBP because all the original 8 3/4 a body rearends were SBP.
