340 Fender Badge conundrum

I own a 72 early production stripper 340/4 speed car. Cloth interior and rubber floor mat, only option is power steering.
The badging is the pot metal Demon Emblems, Dart emblem on trunk lid with no Demon call out out back. My 340 emblems are on both fender sides just to the lower right of the Demon emblems.

There is a good chance the fender was replaced.
