How do i swap in a dana 44 in the rear end of my XJ

so i have a rear end out from under a wagoneer its a dana 44 with the same gear ratio as my front end. and i dont know what im going to have to do to put it underneath my XJ. any help or advice on how to bolt it up or what i have to do to bolt it up would be greatly appreciated thanks guys.

Is this a full size wagoneer? Or wagoneer xj? If it's the later it's a bolt on affair, save for your driveshaft - length will probably be different. If we're talking full size you will probably have to cut off the spring perches and shock mounts and weld xj perches and mounts on in their proper locations.

wouldn't a full size, dont you also need to narrow it?

If its from a 1980+ grand waggy it will "bolt in" to the leaf spring mounts you'll just need to move your shock mounts and get adapters for your D30 bolt pattern.
