What Model # do I use for M1008 in online auto parts stores

Newbie Question:

Looking at on-line autoparts stortes, like NAPA and JC Whitney, etc... What GMC Model # do I use for selection of M1008 parts....??

I don't see any selections for 5/4 ton trucks...

Full size Chevy pickup, K30 4x4 is the civi designation.

As above, the K30 w/ 6.2 diesel is correct for pretty much everything except the alternators and the transfer case, but I doubt you're buying parts for the t-case.
