Are they the same? I just need to make sure, I'm pretty sure they are. My buddy has a 98 tahoe 2wd (badass rig nick names "Escahoe"), and he is wanting to buy my rear axle from me (3.73, auburn), because he has an open diff and 3.42's. But, he'd have to be able to put his axle shafts in my axle. So I guess I could try it, but I'd rather sell it to him rather then somebody else. So thanks bros, I feel retarded.
