A few photos of the backing plate, for reference. Did not see any part number on them.

Karl thought the backing plates are from a 1977 truck with a 12 bolt and heavy duty, JB 5 brake option. The last photo show a '79 brake shoes set on them, and looks like these shoes should work fine. FYI, these brake shoes were used from '78 to at least 87, maybe longer,

The difference in the brake shoe frame holes are not an issue, as Karl had speculated, for '77 and down vs '78 and up from what I see.
