I have not done it, but read the first post here re the door alignment:

From what I can gather, it is important to keep the part of the seat that keeps the door aligned intact. In my regular model 2720, it appears to be the bench seat itself along with an upholstered piece above it that the cushions are retained by.
I'd be curious to see what the factory would say about this.
