Parking brake cable question

[sethv]

Hey guys. Posting for a friend who has a 1984 K10, sits on a 76 or 77 frame and axles. He has no cables or anything and needs them.

My question to you folks (Told him I'd do some research lol) is should he get the cables that come from the cab (from the foot pedal thing) for an 84? Or are they all the same? And where could brackets that the cables connect to be located? Nothing is there at all.

Thanks guys.
