What MRZ Performance parts would fit my Buick?

I was just on the MRZ Performance site and saw that they have tb's and underdrive pulleys for 2.8's and 3.1's. I would think that any 3.1 tb under the chevy, pontiac, or oldsmobile title would fit my buick. They don't have any Buick models in there. They would fit right?
And what about the engine mounts and sway bars? All i can do is look at the parts and see how they are going to bolt on and see how mine are bolted on in my regal and compare the pics to how it is under my hood. But does anyone know which sway bars or engine mounts from another would fit?
