´68 BB Radiator Finish?

Radiators were painted before they were installed, so they were all black with no overstay anywhere. The radiator support is all body color except for some models that painted the front of the support flat black to prevent the body color from showing through the front grill. Hope this helps.

Thank you for this info.
There was one odd duck in 1968 that had everything in gray primer till engine compartment got a hurried black paint job.
I´m trying to recreate one. We know them as the SS Hemi A-bodies.
