Excellent writeup I really enjoyed reading it. I have done some duster hoodscoop research too and it supports what you are saying. Can you clarify the availability of the twin scoops on a 1971 duster. Were they only available on a twister? Or could you order a 71 340 duster with a blackout hood and scoops? To date, I have not seen a 340 duster with a factory installed scoop (lots of owner installed ones). Back in the 80's (before all the "restorations") the only dusters I saw with the twin scoops were twisters, never a 340. But I am still curious if it was possible to order a 340 duster with scoops?.

correct...340 dusters never had the scoops no matter what year. the twisters were the only one to recieve them....whoever the dealer could install anything, if you wanted to pay for it!

Also could you comment on the rear wing availabilty on demons and dusters. Sometime in 71 the trunk lid got changed to the center rib type which doesn't allow the factory spoiler to be attached properly. My 2-70 340 dusters (which I still have) had the flat trunk and my 71 340 duster (which is gone) had the rib type trunk. So what is the deal with that..

i am going to assume by rib you are refering to the seam that runs down the center of the trunk lid. trunk rib thing is something i have never looked at. i thought the trunk lids were all interchangeable? at least 72-76 anyway. i know i have a 72 demon. it has the rib running down the center. i have a factory 71 wing on it that was installed by the selling dealer in 72. i have no fit issues with mine. i rallly don't see at to where there would be a problem to be honest. i have seen wings on many different a-bodies form 70-76. both the 70 style and the 71 style.

Also on the discussions of hoodscoops, if you look in the parts manuals for the demons and dart sports with hoods scoops, the hood panel has a different part number than the standard hood. This makes sense as the hoods have the holes cut in them. Another interesting factis that the grommet that fits in the hole is called a rain guard (or something like that - I'd have to look it up again to get the exact wording) So I am thinking it is just to keep water from running through the hole, there was never any intention to seal it to an air cleaner assembly, just my thoughts anyway.

this is also correct. however i have an article somewhere that i have not been able to find, that states the original idea was to have a fresh air setup for these cars. the insurance regualtions of the day along with the impending fuel crunch stopped the development of it fully. the holes were however left in so the end consumer could set it up themselves. this is why they had the rain guard gaskets.
