Thanks for the help. Im just looking to know if I strictly have to go with a gu5 rear end or if I can install something else. I want something that will drop right in.

Hello Guys need some help. I have a 2007 gmc sierra classic 1500. It has a gu5 rear end that took a crap on me. My question is, is there any other differentials i can swap without having to modify anything. Im looking to get a replacment at a wrecking yard but cant find a gu5. I dont care about hauling or my truck being faster or fuel effeciency. I just need the thing rolling again. Please any help would be appreciated.
