Re: 1964 rear drum backing plates interchangeability
All truck 12 bolts from '64-'82 and truck 10 bolts from '79-'87 will have backing plates and internal parts that will work on your '64 housing. You can stay with the 2" wide shoes and drums or upgrade to the 2-3/4" wide shoes and drums. For the 2-3/4" wide shoes you must have the correct backing plates.
