Keegan B's hood scoop is known as the 1970/1971 era Sox & Martin pro stock hood scoop, I have two, they came in several sizes. I have one that is the largest and tallest offered and one that is about 3/4 of that size (smaller). I may sell the smaller one,it is used and has been mounted and removed from a 70 Duster hood, if you are interested in buying and would like some photos let me know.
