Default 4X4 front diffs

Couple of questions:
Does a 4X4 with a 9.75" rear diff come with anything different in the front diff than an 8.8" equipped truck?
Does anybody make an aftermarket torsen style front diff compatible with our trucks and 3.73 gears?
Will a Raptor carrier fit without modification?
If I install a front diff I'll probably just use the OE gearset on the new diff.

To my knowledge all the front diff housings are the same and yes, the stock gears will work with an aftermarket carrier but you may have to adjust ring gear side to side with the shims to get the right backlash. pinion depth should not change.
