im gonna take the rear finish panel (under the decklid between the taillamps) off of my mustang and weld up the holes, my question is..is this panel supposed to be flat between the lamps or does it have some curve to it, and around the gas filler is it supposed to be raised or flat? mine took a small hit on the rear bumper and i just dont like the finish panel and want it gone! thanks in advance!

 

flat and the gas neck is raised

 

Yep it's flat
