Our AX-15 came with a flywheel. It also came with a clutch that looked like it was in good shape, but we couldn’t bring ourselves to use it. We had the flywheel resurfaced and invested in a new clutch and pressure plate. We also had to install a pilot bearing in the crank since our donor was originally in front of an auto. Don’t forget that you need the aluminum plate and inspection cover that sandwiches between the engine and tranny.
