If I remember my rear axle on my 1 ton had brackets but nothing on the frame. I replaced my rear end with an 85 1ton rear and trying to come up with a simple solution for mounting. I'm looking at using 85 1ton rear shocks from NAPA, making new brackets on the axle and a bolt in crossmember to bolt them to. Also trying to see if the 85 had mounting brackets that could potentially almost bolt into the existing frame?
