Dart 340 twin hood scoops
The scoops were an extra cost option on 340 Dusters/Demons.
Strangely enough they had holes in the hood on the Demon and
a rubber gasket around it BUT were cosmetic only with NO hole
on the Duster. They were standard only with the "Duster Twister"
(Still no Hole) BUT it was only available with a 318 and NEVER a 340.
