Hy Apache1, I don't know if this will change anything with the adjuster, but if that cable that appears in the right lower area of your picture is the emergency/parking brake cable, then your brake shoes are on backwards. Your primary shoe is on the rear and should be on the front.
The shoes straight out of the box are identical side to side...front to back...not sure I follow. E-brake hardware was not disturbed during rebuild and btw they are not connected under the truck.
I read where this linkage in question had to be tweaked before on older GM vehicles, in order for the adjuster to work?
