C9243 Gasket transmission countershaft end plate. Fiber

This Cometic transmission countershaft end plate gasket is precision die-cut from .020-inch premium fiber composite material that resists high temperatures, creep, and fuel exposure without requiring re-torquing after installation. The gray fiber construction clearly displays the Cometic logo printed across the surface and provides excellent sealing characteristics without the need for additional sealants. It directly replaces OEM numbers 36025-36 and 2307-36D, fitting 1936–1964 Big Twin and 1936–1948 74-inch Flathead models. Completely asbestos-free and dimensionally stable, this high-density gasket is ideal for rebuilding four-speed transmissions or stopping persistent leaks at the countershaft end plate on vintage Knucklehead, Panhead, and Flathead motors.
