Back side of a full quarter panel?

[PA Dodger]

I am looking at the full quarters to replace the ones on my '69 Charger. I'm getting mixed answers about the back side of the panels, specifically the area that runs to the back window and down to the trunk filler panel. Do the full quarters end at the top edge of the buttress or do they continue to the back window? I know there used to be a triangular panel you could buy to fix this area but I don't see it listed anywhere anymore.
Thanks

  Full quarters go up to the roof,back window frame and replace the triangle piece you mentioned and down the edge of the trunk. You may need the trunk gutter depending on the amount of rust you have.

Thanks HH. I can't find any good AMD pics that show the back of the quarters. Someone at Stephens Performance said the back is a separate panel and another said it was part of the AMD quarter.

  The piece that is flat behind the rear window is separate and the trunk channels are separate also .If you use "skins" they only go over the main body line.
