Did you try Todd from Prince Albert? 306-764-2246..I bought my cowl hood from him and was very pleased. He sells new hoods at a reasonable price, he also has bolt on cowls for stock hoods, and hoodscoops!
Just curious? What kind of E.T's are you pulling with your stang? And what are you reving at at 100kph with those 4.30's ?
Good luck finding something that works! Jim
