'68 B'cuda inner (plastic) grill detailing tips?

Very cool with the reference pics. I had a set years ago but never thought to look for different part #. Neat seeing "chrome"
Yes, definitely two different part #'s and finishes, pretty rare i think, don't want to screw them up! I've had them for, (embarrassed to say how many ) years, stored and wrapped in bubble wrap. recent recovery from surgery, & retirement has given me time to (try), get the poor girl back together.
