I have an 8.8 in mine and have built several for other TJs as well. It is a great axle but you will need an aftermarket bracket set $300 and someone to weld it up for you if you can not do it yourself.
A Dana 44 from another tj will be a direct bolt on, but you will need to make sure that your gear ratio matches the front axle.
