I've read everything here, but cant find specifics. Whats this "care package" all about?

Im considering this truck for parts ONLY, I specificly need the tranny and driveline but Im not buying a cen gen until I find out more pertanent information.

If the cen reps/owners wont/cant assist me any further with details then I'll have to reconsider the MGT or LST for donor parts.
