8.8 housing help

Ok so im in the middle of aquiring the parts needed to build my rear and i found a new 8.8 housing and was just gonna get that and use that to put all my new parts in and then swap the rears. my ? is that the housing i found was originally equipped with 4 lug axles. Are the housings any different or was it just the axles themselves that were diff. Just want to make sure before i get it. Thanks in advance:SNSign:
