go to the old chev manuals on line and check out the gmc truck manual. there is a better picture of the rear bendix brake set up in there.
i just redid mine. the only things in the rear for the parking brake is the lever that is biolted to the rear shoe and the spreader bar that pushes the front shoe against the drum.
i also figured out what parts go where by checking out the various parts catalogs on line.
i'd send a pict of my 53 3/4 ton rear brakes if i was home.
