The picture I posted before was for a D44, not my D60. When I saw the confusion, I looked into it a little more. There are some early model 1/2 ton two piece with just a tin dust shield. It looks like the 3/4 tons are only one piece unit like I pictured. Although the 1/2 & 3/4 ton 1-piece backing plates look the same, I'm assuming they are slightly different due to the difference in size of the calipers and rotors.
