Quarter panel removal?

KBS is suppose to be the same as por-15 and that's what I was going to do.Thant's the easy way out, guess I'm going to take the quarter off already drilled all the spot welds for the floor out! Such is the way with north east cars I guess! Were you able to reuse the quarter and how about the area ahead of the trunk that 6-7" seam?
Thanks!
