Quarter Fitment Problem

I'm having a hard time seeing the problem.

1968FormulaS340,
If you go back to the first pic in post #6, I am talking about the three plug weld holes in the middle of the pic. You can see the shadows from about 9:00 - 12:00 in the holes that indicate the separation between the two surfaces. The right angle bend in the trunk extension is too far toward the rear of the car to allow the bent flange to mate tightly with the lip of the wheel well. Thanks. L8r
