@vic1212 You don’t need to order parts based on VIN… just go in there (or call), tell them the part that you need, and have them order it, since they will most likely not have it in stock. If they do, even better.
Getting the part isn’t the difficult part of what @tom21pa wants to do. Rather, the challenge lies in actually making them work with the vehicle’s “electronics”, as in DIC, power, etc.
As for swapping the 3.0 LF1 for the LFX, I’m sure it’s possible. But it’s a matter of how much money you want to sink into it. Might be less expensive to just get a new Equinox/Terrain with the 3.6 in it already and trade in the one that doesn’t.
