Diff swapping

I have a 92 and 93 4runner, 3.0L, auto 2wheel drive I'm building for my teens, both have 32"-32" tires, my axle code is G072, witch tours out to he 8"/3:90 ratio/2 pinion.... basically the 4 cylinder rear ends...in both of them..just my luck...I just bought two new used diff's, ones a 4:56, 4 pinion v6, and the other is tue G144, factory 4:88 4 pinion, out of a 4x4, does anybody know if these diff will just fit in my G072 4 cylinder 8$ housing that came stalk in my v6 4rnners fir some reason? Thank you
