As to the emblem on the fender, it is a Commando V8 emblem. Also used on other Plymouth cars with a 383 or 440 engine. Dodges got the 273 4 barrel emblem.
I knew about the emblems on the Dodge and figured that was the emblem I saw in the picture, but it wasn't clear. That same Commando emblem was used on 66 and 67 Barracudas with the Commando 273 and without the Formula S package.
