One thing to remember, as Mother Mopar got further into the 70's, lets face it, quality control went downhill FAST> Just read on the F body forums. (77-80 cars). We love the suckers, BUT I admit I am lucky to have one that lived in a dry climate and never rusted!
If you can see body color thru the grill, personally I would black it out. No big deal as I see it.
