Yeah I put the cable in between them because that diamond shaped thing is loose and it wouldn't stay put when I tried to put the spring on after.

The truck has 11x2.5 brakes and that's what the crossbar and adjuster are from. In this pic you can see the pivot is pretty far from the shoe though, I guess the cable is too tight? It is released all the the way though, in fact the frame bracket cable isn't even hooked up right now so everything is loose.
