The deal is that the 2 wheel drive pickups went to 5 lug wheels and
front disk brakes in 1971. The 4x4s also went to disk brakes, but kept
the 6 lug pattern.
I expect the rear brake pictures in the 71 manaul show 6 lug axles
because there was no reason to change the pictures just because the
number of wheel studs changed...the rear brake service methods stayed
the same.
