1964 rear drum backing plates interchangeability
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 |

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.

The backing plates and drums are different for the 2" wide shoes than those for the 2-3/4" wide shoes. Either will bolt to a '64-'87 10 or 12 bolt truck differential.

Sorry I don't have any pics of both backing plates on this computer. I would have to take a couple pics and post them tomorrow.

the backing plate for the 2 3/4" should have a deeper recess where it goes back over the axle flange I would imagine

The 2" on a 66 differential. I hope the picture attaches.

I found some time to take pics today. The first two are of a backing plate for the 2.750" wide shoes. Notice the deeper recess where it is bolted to the axle tube flange.
