Boss 351 clutch/flywheel size

1mach1 · Nov 20, 2014

I eventually need to replace the clutch and flywheel assembly in my Boss. Does anyone know which is the correct one? It seems like it is the 10.5", but I cannot find any definite answer on the web. Any help in this matter would be appreciated. Thanks!

The Factory Service Manual says that all Mustang 351 2V and 4V engines, 3 and 4 speeds have an 11" clutch diameter with 9 springs. Pressure Plate is also 11" with 8 springs.
