whistle driving me MAD.

:prayer:Hi all. I am trying to find a very anoying whistle on a 68 dart rag top. I always liked the look of the bulge hoods so I stuck one on. It looks great but now I have a damed whistle. It starts at app. 20 mph & up & will eventually go away when you get her up to 60 mph. The funny thing is I also had a 69 dart & changed the flat hood to a bulge hood & had the same issue. WTF but never found the issue & eventually sold it. Now here I am back to the same issue. Has anyone had a simallar issue ???? & how did you fix it??? I have tried everything, took off the inserts, took off front chrome, ect,ect, On a seperate note I met Daisy Duke @ Carlisle she is still hot. Thanks
