Changing the rear quarters on my Dart conv. from a 69 to a 70

I have the quarters, the rear panel, the bumper bracket supports (the trunk pan is the same from 67-72) ,the rear panel and the trunk lid, bumper and brackets, so all I need as far as information is I would like an idea as to where would be a good spot to add the 70 1/4 panel to the 69 1/4 panel. I can figure it out but I was hoping for pictures to make my decision easier. The 1/4's on the car are in good shape so I really don't need to do the full quarter only the transition area from 69 to 70 at the very end of the quarter where the 69 to 70 change begins.
Frankly, if You've got full OE style quarters, You should put them on. Do a nice job of drilling out & separating the spot welds, & sell the nice full '69 quarters to somebody who needs them, I'm sure there'll be takers.
