Rats. It appears you're going to have to visit the dealer and look at the drawing on their computer. I can't tell from the pictures in the service manual but I can describe the two methods they used on the older trucks.
The really old ones used a simple cotter pin; well, at least they could. Those originally came with a wire pin that was formed into a circle to hold it in and to give you something to grab onto. As I recall, I think they called that a circlip. Cotter pins worked just fine. The newer style used plastic inserts that were snapped into a hole in the lever, then the big steel adjustable pin snapped into the insert and "magic held them together". The insert was damaged when you pried the linkage apart so you were supposed to cut the insert out and snap in a new one.
The first time I saw one of those inserts, I couldn't believe that would hold, so I cut it out, welded a bolt to the pin to make it longer, then inserted it into the hole on the lever and used a c-clip to hold it. That worked fine for many years.
