The BCM is a direct swap. The two issues you will have are your millage will change to what's in the BCM already and you will now have the factory alarm system. I say that's a bad thing because (although not a huge deal) if you lock the car with the RKE remote and unlock it with the ignition key, it will set the alarm off. The 300M's and other LH's that had factory alarm had sentry key sensors in the door(s) and trunk to make sure a sentry key is being used to open the door.
The Special cluster is a direct swap, especially since you already have traction/ABS. Your only problem might be if the car that the cluster came from had side airbags, you'd get a light. I have a few spare clusters if you're interested.
