The 8.8 is a great swap if ya look hard. I lucked up n found one in a wrecked tj. It already had the brackets and 4.56 gears for $500. The guy selling it has had a jeep shop all his life n thought it was a factory dana 44. My buddy who found it turned it down cause he wanted a oe rear. He found a dana44 out of a tj for $600 from a guy who was parting it out. You can find good deals if your patient and look close. Craigslist is good, forums n sometimes junkyards. If you don't find one already set up figure in brackets, gears to match front, and driveline if its different. I just swapped wagoneer dana 44 front in n it took a long time. I made all my own brackets n did the welding n everything. I saved a good bit of money but if ever again ill buy a kit or truss. Not sure where your at but the atlanta craigslist usually has a lot of jeep rears already set up. Either way good luck n plan ahead. If your going big take your time n do it right once. It's taken me 12 years and 4 jeeps to figure that out.
