You are correct. For the wires on the vertical and horiz. stab you use 1/2 of a metal clevis. You break off the side with the pin in in it leaving the hole side for putting the bolt through. You will have to drill out the clevis hole because the bolts are larger than the hole. This will be done for for all of the clevis's so set yourself up and drill them all at once. This is a real PITA as the metal is hardened and it takes quite a while to drill through them. Be careful not to push too hard or you will heat the metal up to red hot and it will break. Once you get the clevis's drilled out, you should be able to assemble the flying wires and attach them to the hard mounts on the stabs. (Hope this helps your progress.)
