Yea, some guy did - there is a thread on it here, somewhere. But he is quite the handyman, as I remember it - you might search this, the Crossfire Roadster section, for the thread, but I cant remember the title of the thread.

I think some specialty tools are needed, if you read in the Service manual section on the convertible top, it talks about the procedure.

There is no alignment of the hydraulics to do, but fitting the top to the frame is a bit tricky - but it does not sound impossible.
