What years did rear brakes come with 10" drums

Have a dif I'm about to do rear brakes on. It is big bearing but 10/2.5" brakes. Anyone know what years came with this setup. Just want to make sure I get correct parts.
Thanks

Those were available in 1974 and 1975 depending on the GVWR.

It is the medium duty rear axle. My '74 Ranger has one.
