I have a fiberglass hood scoop that looks like it could be from a demon but not sure. It has what looks to be a chrysler emblem, letters FP, and two sets of numbers on the bottom side. It looks exactly the same as what came on the demons. If anyone could help me out it would be great.  

I believe '71 Demons had the twin scoops, it sounds like this is the '72 up Demon/Dart sport single scoop with two snouts.

If that's the scoop you're talking about, the factory originals were two pieces bolted together. There are also aftermarket versions of this same scoop, but the aftermarket scoops are one molded piece.

If your scoop is the two-piece version, it's a factory scoop.  

Its the single with two snouts and its a two piece the local car guy said it was a original and offered me 50 bucks for it , would you have any idea what it would be worth, its in decent condition but all the studs are pulled out and busted off  

Pn# 3672605 thats the original Pn , i used to sell afew of them, 50.00 tell him bound sand try to find a original one used. there are replicas of them out there though i havent seen one. There are alot of advantanges to this scoop 1 is you can see over it.
