Is there a wheel house patch and a quarter panel that you are installing? In the second picture it doesn't look like your quarter is pulled in tight to the trunk drop off. Is the wheelhouse patch holding the quarter panel out?
I would remove the wheelhouse patch and clamp your quarter to your trunk drop off and make a template of what shape the wheelhouse patch should be. Might have to cut the flange off of the patch and reform it.
