CSX2287 one of only six Coupes ever built and the only one built entirely in the United States. MacDonald and Holbert drove the Peter Brock designed Coupe to a 1st in GT and 4th overall finish and broke Ferrari's 6yr stranglehold on the Grand Touring Division. This was the first win for Shelby’s vaunted Daytona Coupes.
