Charlie Brown,
I purchased to vinyl wrapped cables and found out they are not an exact match to the original. The original cables had an inside and outside plate that mounted to the brake plate on the rear end housing. The vinyl only come with one. It took some messing around, but I finally got mine to work. If you give me a couple of days, I can try posting shots of the linkage underneath the truck. If you run into trouble with the hardware, I could pop a drum for you and take a shot or two of that as well. Let me know if you need more help.
