I made the threaded ends from pieces of 5/16" fine threaded rod. I cut the rod to the length of the originals and then drilled a 1/8" hole into the rod about 1" deep. I cut the ends off the cable and pulled the cable back into the housing so I could cut the housing to the correct length. Then pushed the cable back through the housing and cut it to the correct length. I heated the end of the threaded rod red hot and then pushed the cable into the hole. I cut a small notch into two pieces of 1/2" steel and laid the area to be crimped into the notch. Using the other piece of notched steel, I just hammered them together making a very secure crimp of the rod onto the cable.
The 5/16" fine thread rod allowed me to use the original clevis assemblies.
I don't remember the cut off length of the cables. Just hold the cables up to the mounting brackets, leaving a bit of slack and mark them.
Toughest part of the complete swap was making spacers to hold the cable housings in the AD brackets. After you cut off the cable housing there is nothing for the bracket bolt to clamp onto. I took 1/2" round stock and cut it to the same length as on the AD cable housing. I first drilled a 3/16" through the entire length of the rod. I then drilled a hole into the 1/2" rod just large enough for the cable housing to go into it. But don't drill this hole through the entire length of the rod, stop about 1/4" from the end. This provides a stop for the cable housing to keep it from sliding through the clamp when you apply the parking brake.
I then used a cut off wheel to cut a slot down the entire side of the rod. This slot allowed the rod to tighten down on the cable housing when the bolt in the bracket clamp was tightened. You also have to grind a small notch in the side of the rod in order for the bracket bolt to clear the rod.
This entire conversion made for a very original looking parking brake setup. Even the "experts" dont usually notice the different rear axle setup.
I know this all sounds a bit confusing, but it was really pretty simple. I do have pictures of the entire operation and if anyone would like to see photos of some of the details, email me and I can send them to you.
