Service bulletins have some good illustrations. I use the Digital set on a CD from Dave Graham-Auto Literature, Inc. Brake parts and linkages are also a part of the assembly. The radius rod, axle, spindles. spring perches, spring, and shackles are the main parts of the assembly. The stuff I always wanted to know was proper orientation of the king pin pieces and their lock bolts, the grease fitting orientations, as well as putting all the brake parts back together.
