Getting spare parts - front differential, transfer case and rear end

[dictum]

Are these parts listed above from a 2007 Denali compatible with a 2013 Denali XL?

On the differentials, as long as the axle ratio is the same (should both be 3.42 if they're Denali's), then they should be interchangeable. The transfer cases should interchange as well. Both my '07 and '12 have the BW4485.

thanks, this is helpful.
