Has anybody done a shackle reversal on their jeep without buying a kit to do the modification. I'm wanting to a shackle reversal on my cj-7 but I have a few questions, like where the front shackle mounts to the frame how do you know how high to mount the shackle. Also what is the best shackle angle. I've searched all over the internet and found many different angles like 30,50, and 60 degrees. I hope someone can help me on this board, I think this site is the best for info. Thanks for any info that you can give me.
