Ok all you 4x4 guys, I want to replace my fr. diff and rear axle w/diff. I am wanting to go 3.92 and want the best (not nec. the most expensive) 4x4 performance per $. Also needs to be plug-n-play (if you will), I want to be able to just swap it myslef and I want it to work with oem electrical. Thanks guys. Pics would be nice too if you have them.
