bushings are not interchangeable. I currently have stock waggy springs up front, but am switching to lifted (2.5") YJ springs. the stock front hangers will work, but you need to bend them out a little bit or shave the bushings. I bent mine out. it's the same deal with YJ springs. my rear shackle on the front springs are (I think) Taco shackles from AOR. Talk to Randy and hopefully he'll remember what I ordered. They work perfectly. I'm not happy w/ my pinion angle, so when I swap in the YJ's I'm also putting in a set of 3* shims from Roger Brown. let me know if you have more questions.
