The use of TWO clamps is good and the idea of a longer center bolt is also good, BUT in my case I had to flatten the spring to get the shackel bolts through the holes so while both shackels are in the eye-ends my spring was still under tension! I did this by putting a block of wood under one of the eye-ends with the other end bolted together and then clamping down in the center till the spring was flat enough to add/remove the shackel bolt because the spring needs to be flatter to make it longer and take the tension off the shackels. That could be done more safely, I admit, using the long center bolt idea and if you remove the original center bolt I guess the leaves could separate, I did not try that. You might have to take extra care to put the teflon buttons back on a Super-slide if you take the leaves apart. As long as the leaves are bolted together, the arch will have to be flattened to get the shackel bolts out. Hey, I usually have to do things "my way" pretty much as learned from my Dad, and eventually I may do something wrong and get hurt but so far I guess I have either been right or lucky!
