Hi, Just bought a truck, -68 C-10 Longbed 2wd, that missed the parking brake wire that connects the front wire to the wires from the drums. I'm not sure how this thing should hook up front and rear...does anyone have a picture of this area that could explain it better? With the truck came a little box with bolts and other odd things, a u-formed piece that I believe has something to do with this. Thanks for help!
