The fender wells needed to be modified where they bolt through the subrail, on the original fender wells they had indentations at the two bolt hole locations so they needed to recreate the two indentations on the reproduction rear 1/4 panels.
Here is a closer photo of the two bolt hole indentations.
They also installed the cage nuts onto the inner fender so the fenders can now be bolted in place.
With the cage nuts installed a coat of Dupont DTM Epoxy was sprayed on the inside of both rear 1/4 panels.
