Need (PLYMOUTH) emblem

I think you can still get them new. Try searching for the part number on Google. The part number I found on mine was P2785791 "Plymouth“ Nameplate Emblem (1970–72 Duster Hood, 1968–69 Road Runner, GTX Hood). Now mine goes on a 68 Barrcuda but it might be the same. Another part number might be P2998042 “Plymouth“ Nameplate Emblem (1970 Road Runner, GTX Hood, 1971 Barracuda Hood).
