I am super impressed with the quality of the brackets and how well they fit with what I am sure is a wide range of tolerances from the factory. Are you installing yourself? I have a few tips in case you are. Stuff that I found that worked pretty well
In the front, definitely start with the driver's side. I think I had the bracket in and out for fitting maybe 5 times. I went through and installed everything and realized that the res hose was touching the plastic, so I took out a bit more plastic but not totally sure it was necessary. On the passenger side, a TON has to get cut away. Before you get it on jackstands, pull the battery. Its right there in the instructions and for some reason I thought I could be precise enough with a dremel that I wouldn't need to do it. I was wrong. Pain in the ass trying to pull the battery when the jeep is way the "f" up there on jackstands. The next hardest part was drilling up in the spring bucket. I ran a small pilot hole with the plate in place, trying to center everything in the holes. After the pilot holes, I drilled the first one by just laying under the axle and used all arms. It was an awkward length from my body and tired me out pretty quick. I ended up rigging this up instead....

I know it's probably not the safest, but it was a lot easier to apply a little pressure to the clamp and keep the speed down on the bit. The good part is that the holes in the spring bucket matched up perfectly with the lower plate and the tower. Bolts literally fell in to place.

In the back, really the only two tough things are getting the body up high enough to get the reinforcement plate in. The exhaust hanger on my passenger side had to go up quite a bit more than a quarter inch. Make sure you have a long pry bar for it. The rockstars are a little tricky. I put the axle up to the bumps and made sure the johnny joint was pretty neutral so the arm would move easier. Dropped the arm for the cuts, and then put a jackstand under the arm when you are putting the rockstar up for the final time. One of the small (3/8" in think) bolt goes in from the front of the mount. I used a small piece of flat stock from the top of the mount to keep pressure on that bolt while I slid the rockstar on. I just realized I typed a frikking novel about a bolt, but the first one I did I literally was holding up a control arm with my leg, helping the bracket up with a rubber mallet while trying to "will" this tiny bolt to not fall out. My daughter walked in the garage and heard a lot of words she's never heard before....
