Way back in 1978, when you could still order them through Chrysler-Plymouth dealers, I ordered a new center and headlight buckets- they arrived in a heavy texture dark argent, like the '71s.
I was pretty disappointed, but Evidently that's what they had on hand for crash parts. (* edited the strikethrough based on MoparCarGuy's note below). I've still got them in the boxes in my garage.
BTW- just looked them up, with my discount at the dealer, the grille was $35.47 and the buckets were $13.99 each. I should have stocked up.
