This link can give just about all the info you will ever need to build an 8.8.
The 8.8 is not a direct bolt in unless you were to either buy one that was already built by another jeeper or if you bought a new one from www.ok4wd.com
which sells them ready to bolt into a TJ.
They can be found pretty cheap and they are only about 5/8" narrower than a TJ axle so the track width is very close. Its been my experience that you will find an 8.8 much sooner, cheaper and more often than a used D44 that you can bolt right into a TJ as most guys do not want to sell that axle. The 8.8 is very strong and has a good aftermarket backing so you can go wrong with it if you went that route.
