I have a '69 hood with a similar scoop I put on it back in the day, was from a '84 Capri RS (same as Mustang I'd imagine). From my dearly departed "Cleveland Rocks" '70 HT (with a '69 front end). Looks good but had to make additional/different holes in the hood understructure for the nuts. Cut out the front of the scoop and the hood for functioning Ram Air and I was living large!
Wouldn't mind selling this hood/scoop if anyone is interested.
This time around (Isabel), I went with an original (for stupid money I might add).
