swapping in an E locker axil

I have an 03 XE Xterra, will the 05 and newer E locker dana 44 fit my model? or will there be big modifications. I was also wondering about the gear ratios if they have changed at all. Mine is and automatic. I mean a total axil change, diff, brakes, etc the complete unit. Thanks!

wow, no comments? Come you guys, I know you have some thoughts. I live in the Republic of Georgia (Eastern Europe) and there are a lot of xterras here, A guy told me he had a complete rear axil from a crashed 06 with an Elocker in it for 800 bucks! That's cheaper than buying a ARB and it is break drum to break drum complete. I just need to know if anyone has tried this before or knows if it is an easy fit. Thanks!

I was thinking of doing this with a Toyota 4runner axle
