also the same assembly on 1/2 ton, two wheel drive pickups with the 4 1/2" bolt pattern.
i'm "assuming" you are referring to the rear drums ?

i just looked in my wagner master catalog, and the B & C 11x3" drums are different part numbers.
that leads me to a couple of conclusions.
the spindles have different inside bearing sizes, or the brake stand-off is different between the backing plates of the B & C bodies.
now i haven't looked any of this up, just looked at the wagner part numbers.
does this help any ? shruggy

correct. the shoes, springs, etc, are the same, just the hub/drum assembly is different.

I have a few sets of 67 B-body front 11" drums and backing plates, I was wondering if they were the same also, so this helps! My assumption is that they are the same 67-69, correct? shruggy

The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.

Yup. 11x3 was the HD option. Have a 70 and 71 GTX cars with them.
