1964 rear drum backing plates interchangeability

[88k5jimmy]

Long story short, I need the backing plates and all non reproduced parts for a 1964 12 bolt. Are there newer years that interchange with the 1964 that might have better parts availability? I read that maybe 10 bolts up to 1987 would work as long as they had 2" drums. If that's the case will all the other brake parts connect such as e-brake cables from the 1964 to the newer backing plates and internal components? I'm assuming if I were to use the backing plates and non reproduced parts from a newer 10 bolt I would still be able to use the 1964 internal brake components and 6 lug drums as long as everything utilized 2" drums/shoes?

Thanks
