Approach with CAUTION Simon! All of the vendors can supply parking brake cables, but unless they've found new sources, all of them that I've seen for the 1/2-ton trucks have been to short. They're just long enough to reach the backing plate and leave absolutely no slack for the movement of the rear end. Also they're to short and the bracket that's riveted to the frame can just barley grab them.
There was and article about Inline Tube in Classic Truck magazine back about a decade ago. Said they custome make brake cables to your exact dimemsions. I'm sure it would cost a bunch more than those from the standard repro vendors but at least you know they are going to fit, and to me that in it self is worth twice as much.
