Sorry, I was referring to the part number for the big daddy RXT kit. 6918.07 that includes the flywheel as well.

Even that is a rip off. That's exactly what companies do. Say it's for a GT500 even though it will fit other applications but because it says GT500 they double the price. What a rip off!!!
