starting in 71, they added disk (as stated above) but that is also when they went to the 9/16 studs. You coupl probably get the rear hubs and drums off a 71 - 72 rear and put them on your truck if it really bothers you.
Just getting studs won't help. you'll need to redrill and spline the hubs, and then redrill the drums too.
