What size rear brake drums on 440-6 E Bodies?

What size rear drums did the 1970 440-6 4 speed Dana 60 E Bodies come from the factory with?

What about the 71 440.6 4 speed Dana 60 E bodies?

What about a 70 440-6 auto with a 8.75 rear?

Did the track pack or super track pack have something to do with getting bigger brakes? Or was it just the rear end gear ratio?

Thanks!

If you had drum brakes you 11" brakes all around.

If you have disk brakes you had 10" rear drums (the exception to this is AAR/TA cars, they had 11" rear)

Super track pack required disk brakes.

What width were the original 10" drums???

And what about the 11" drums on the TAs/AArs? What width were those???

10 x 2.5"

the TAs were 11 x 2,5?

Yes, in short words.
