Would anyone know what the difference is between the Screaming Eagle Performance Clutch Hub kit P/N 37976-08 and Compensator kit #40274-08. Both numbers are listed in the Transmission Self Help Tips section under compensator kits. Both parts sell for the same price. But 1 part number does not sub to the other. At the same time they look interchangeable. I'm looking for a SE compensator kit number to fit a 2009 Dyna. Tks! Found the answer. It was in the 2010 catalog.
