Before I found JR I had a broken cable on my '84 but nowhere to get any so I made a set of my own. It's not to hard. The single most important thing is to but the CORRECT cable. You need HI strength(aircraft type) cable. It has smaller but many more strands of high strength steel. You can get it at H/D along with the necessary hondos(little loops on the end that the upper half bolts go through) cable clamps and eye bolts. As a matter of practice, whenever one aged(25+ years)componet fails, I replace all the other similar componets simultaniously, so I replaced all 4 cabels, even though only one broke. Probably took 2-3 hrs., due to it being my first try. Cables must be destalled(is that a word?) and installed with either the top all the way DOWN or fully supported with blocks at the corners that take ALL the weight. Just be carefull that when you detension the cables by loosening the eye bolt nuts, the cables become very slack. If the nuts get to within 1/4" of the end of the threads and the cables are still tight, STOP and find out why the top is still pulling on the cabels. It must be FULLY supported. Once the cables are loose, you can remove the clamps(there should me at least 2) and remove the cable from the eye bolt. Thread the cable back through the pully on the cylander arm and all other pullys back untill you can remove the bolt that attaches the other end of the cable to the top half. Install the hondo in the new cable, bolt it to the top half and run the cable back through the appropriate pullys to the eye bolt. Do the same for all the other cables. If the top is Down, RETRACT the hydrolic cylander all the way in. If the top is up, EXTEND the cylender all the way out. Pull the cables taught, tighten the cable clamps, making sure the tension is about the same on each. Retighten the nuts on the eye blots. Have a helper (code name:copilot)slowly lift or lower the top while you watch from underneath to be sure everything is OK as it moves. Raise the top and check for proper mating clearances. Adjust the top up by tightening the eyebolt nuts and down by loosening the nuts independantly untill you get it just right. Cycle up and down and check again. CAMP ON !!
