In that area it's from inside the car and the area you lined ,you could cut that line then carefully grind off what's left ,once you get the new rockers you will see it a little clearer ,look at the panel covering the rear side window track ,it along with the rocker and floor are spotted together ,you could cut it there but you would still have to seporate the floor ,rocker and inner panel,again take alot of reference photo's and measurement's This is an old photo but it gives you an idea of what I'm talking about.
