That's basically what I did. I didn't see a way of getting it under the roof with some trimming and I see others have had to do that too. I'm pretty happy with the sectioning job on the rocker (from the back of the door to the back). One thing I noticed with both the rocker and quarter is that any misalignment or variation in gaps existed before I started are still there after I finished. I measured and recorded the gaps and took photos before I started. I guess that means everything is installed correctly :)
