Clutch Disc BN1

This is a Clutch Disc for a Austin Healey BN1. It will only fit the BN1 with the Original 3 Speed Gear Box. In reality these early cars used a truck four speed gear box with the granny low first gear blocked out, making it a 3 speed. Another way to tell is the spline size, the BN1 units where a smaller 10 spline by 1 inch. Overall diameter of the clutch disc is 9 inches. Cross Ref.7H3225, CLU105, 591-020
