Please take a minute to tell me if my plan is correct or not

I can recap on what I did and how mine turned out. I didn't do it myself and enlisted help, I am still not sure if, looking back the guy that helped me made the right calls. What we did was similar to what you are saying, we trimmed the new quarter down to fit with the seam just in the middle of the first two body lines coming down from the top. This is the body line that is approximately 1 3/4" and narrows to about 1 5/8" at the door jamb. We didn't go into the door jamb, we stayed 2-3 " back from it , also we didn't go into the sail panel. We did go around the back corner of the car, as well as replaced trunk extensions.My only gripe at this point is, the warpage between the 1 3/4 to 1 5/8 body lines at the top of the quarter, I will be able to straighten the issue out with filler, but it is time consuming. I d not know if it would have been better to stay below this narrow area. For all I know straightening the warpage would be worse in the wider area of the quarter.
