Based on the driving /braking you were doing , and the disparity between brake drum temps front/rear , it sounds like your front brakes may be dragging .
There could also be a bearing issue . When I did the brake job on the '86 I found pitting in bearing races and rollers. Appeared to have fairly fresh grease , I suspect the bearings had been packed and set up with too much preload . In any case, bearings can be a heat generator if there is a problem.
Your call , but I would get the front wheels off the ground and get a feel for what's going on.
Do you have 24.5 wheels ? Not a huge job to remove a wheel and brake drum to have a look. Heavy parts and jacking , cribbing safety imperative.
Oh , likely left hand lug threads on driver's side !
