2004 chevy rear end bent

[Baconfuel]

I have had this truck for 8 months and put 10k on it and now I'm on my third set of tires.
They only wear on the inner tread. Completely bald.
I took it to BeeLine Auto here in Columbus Ohio and was told the housing has been bent.
My question is which Chevy rear end years are compatible?
Have not got much help from junkyards. I want to keep my disk brakes and wondering what works for a straight swap?

Thanks JHT67 for telling me about this sight. It's sweet. Hope you and your dad enjoy the GMC.
