Hey man, i've started up a 71 and 72 dodge demon registry and so far, i've collected tons of historical data and from what i've gathered, there was not a colored grille option in 72 like on the 71 Demon Sizzlers. As far as a 72 Demon Sizzler, i'm almost positive it was a 71 only option. Im not 100% on this, but again, through all of my data and pictures so far, i've yet to come across any 72's with a sizzler or colored grille package.

Good luck!
