You can buy the kits with everything from many vendors online. The Rubicon Express kit fits the Dana 44 well, the Mad4wd kit does not fit the Dana 44 well.
With all that said, if you don't know what brackets you need, you probably aren't ready to build custom longarms. Also, when many people go to custom arms and different axles, they change to a suspension system that offers greater flexibility, such as a 3 link or 4 link. There is a ton of information on this subject out there, especially for TJ's. NC4x4 and Pirate4x4 are two sites that you can learn alot from, but you have to take the time to learn it. Trial and error is an ok method for a part of a system, but your entire suspension system is not a good place for trial and error.
