on my 81 the parts store sold me the wrong calipers, I didnt research enough to know there were 2 different brake set ups for a 2wd. The first calipers were bigger and were like a 1/4 inch away from fitting.
Yes, base trucks got JB1 (manual) or JB3 (power) with 1.04" thick rotors.
A step up was JD3 with 1.29" rotors.
Calipers and inner wheel bearings were also different. Pads were the same.
Did I get this right, Keith?
