69 Passenger Quarter Low?

Everything measures out level (tail pan, frame rails, rockers, roof line). I think the deck lid looks off due to the notorious tail pan weatherstrip channel bending up on the pass side.

Even with the taillights openings measuring level, you can see that the pass quarter is low around the deck lid opening and the body line and marker light are 3/8s or worse too low. Any insight would be appreciated, I'm at the point of trying another quarter.
