No they will not fit without a lot of work. You would have to grind off the coil spring mounts then add leaf spring mounts. Not to mention the dana 44 in a grand is the odd ball 44 limited lockers and aftermarket support. The front 30 if its is v8 also has CV axle's vs u-joints.
I would look for a front YJ 4 banger dana 30. will have 4.11 gears and then add in your 8.8, which will need a bit of work and save for a gear change.
Other option would be dana 44 axles out of late model grand wagoneer, butI can't recall if the t-case diff is on the same side as the YJ, also you would need new rims.
