Anything that isn't from an MJ will require welding perches on. If you want to keep the Jeep front axle, than your options are quite limited. That's why the 8.8 is as cool as it is. Stronger than a 44, disks, 4.10s or 3.55s, almost a perfect width, available posi and Explorers are as common as anything in the junkyards. Even the older drum braked models are just as strong as the newer ones and have much better brakes than the Dana 35.
Here's some good reading on the subject:

And there's nothing great about the Grand's Dana 35 except that it has disk brakes. It's just as weak as your Dana 35.
