NOW, I do believe the SRT and Base/Limited BCMs are different, but I can't say that for sure. If you car is an SRT, get a BCM from an SRT - if not an SRT make sure the BCM didn't come from an SRT.

I THINK I read that the Coupe and Roadster take the same BCM, which surprises me, because the BCM in the Roadster has control over the windows when you move the top.

Just get a BCM from the same configuration (coupe or roadster) and trim level (SRT or Base/Limited) and you should be fine.
