Are 3/4 ton and 1 ton front drum backing plates the same? If not I need 1 ton backing plates, time to hit the J-yard

I have been under the impression that the shoes are the same, and I know the (non daulie) drums are dead on the same. I have a 3/4 ton and one ton drum ont he front of the longhorn as we speak.
So I am 99.9999% sure. I doubt they'd pack the same drum with different parts.
