Parking brake cables

[Stephen717]

Ok so I'm trying to figure out the parking brakes for my truck, I found the cable that connects to the pedal, but the rear brakes are 13" brakes from a late 90s GMC k2500 full floating 14 bolt rear so idk if the 71 parking brake cables will work or if I need the parking brake cables from the later model truck, from there my next question would be do I need the intermediate cable that matched the rear cables or can I use the one for the 71? If anyone can help it'd be much appreciated cause that's all I need other than a proportioning valve to finish the brake system on my 3/4 ton frame so I can move the body over.
