Hy trump, I don't have a maintenance manual that goes back that far, but if it is a full floating rear axle (series of bolts holding the axle flange to the hub) then once you remove those bolts the axle should be able to be removed. If there are no bolts holding the axle to the hub then you are looking at a semi-floating rear axle, that means you'll have to drain the diff. oil remove the housing rear cover, remove the differential shaft lock screw, remove the differential shaft and spacer block, rotate the ring gear and remove the pinion gears. Push the axle shafts in toward the center of the housing and remove the "C" washer from its groove in the end of the axle. You should be able to remove the axles now, they may need to be persuaded to leave the housing, hope that helps.
