Does anyone know if the flywheel from the st185 gt4(Alltrac) will fit on the st205 gt4 engine. The price of replacing the clutch which is the twin plate setup is going to cost to much. My standard flywheel of the 3sge is 295mm in dia, the st205 is 305mm. Also the bolting pattern is slightly bigger on the st205. Hopefully someone has done this before and can put me out of my misery.

ok, I put the vernier callipers on the two flywheels today. The 3sgte has a 2mm bigger dia bolt pattern than the 3sge. Have to try on the engine to be sure, Just incase. Oh yeh and the 3sgte flywheel is 10mm bigger than the 3sge in overall size. Dont know how i would go with the starter motor.
