[flashed]

I just bought a wrecked 2012 Chevy Truck with clean title , Most body panels are dented but no frame damage , doors and cab are good . 140,000 Miles on it and its been hard miles . Its 2 wheel drive , fully loaded , extended cab , with rear access doors , rear end is damaged , broken gears maybe . It runs great .
Will the rear end from a 2003 or 04 Avalanche fit this truck ? I also have the Avalanche as a donor for one of my builds .

I bought the 2012 truck as a future donor but if I can put it back on the road with parts from the Avalanche I may sell it as a runner . Im not familiar with the newer trucks so any info is much appreciated .
