Just wanted to add my EZ-Flex install experience for those who will be doing theirs. When I did the first side, after pressing in the bushings, I noticed they looked somewhat distorted, as if the spring eyes were too small. Then when I pressed in the bolts, the bolts would either stretch the bushing or break it. I went through several extra bushings before I was able to finish the side. After ordering more bushings, I took a different approach. After removing the original bushings, I used a Dremel tool with a sanding drum to clean the rust out of the spring eyes. Then, after pressing in the new bushings, I used a 9/16" drill bit (the same size as the new bolts)and, running it in reverse so as not to grab the bushings, reamed them out. Before installing the bolts, I rounded off the shoulders slightly so they would push through more easily. Using this approach worked so much better that I went back and re-did the first side.
Hope this info is helpful.
