Used Tilton Race Clutch and Flywheel. This was used on a Road Race Car with a Reverse Mount Starter. It was used and in good condition, but has been rained on. I would disassemble and clean or replace clutches. 26 Spline Tilton Part Number 089076. The Pressure Plate Measures 8.5" and the flywheel 10 3/8" overall outside the teeth.
