Any reason why a WJ dana 30 carrier wouldn't work in a high pinion XJ 30? I need a 3.73^ carrier and would rather get one from a JY, most yards around me have shockingly few ZJs and alot of WJs both of which have plenty of 3.73 axles(i think). Also would a trac-lok carrier from a WJ work, wouldn't might a little Limited Slip action for no added cost if I can find it.

 

The WJ Dana 30 carrier will work, but they never came with a track lock, I wouldn't recommend putting one of those in the front axle anyway.
