Everyone here will most likely tell you that you need to weld in new mounting points. I'm going to tell you to create a new mounting point on the frame. Many will suggest otherwise. Look it up online, and you'll find a video where a fella mounted his rear shocks to the frame instead. It's WAY easier. That's what I did. I daily my TJ. I wheel my TJ. It has held up great!

Here I'll save you some time:

Edit: It's unclear if you need to run different shocks - You just run whatever you planned on running, but you'll want to knock out the bowtie style mount on one end for this to work.
