The large open design offers visibility to timing chains and marks allowing timing changes while the wheel is still on the engine. These degree wheels feature a 1 in. center hole to fit with a crank socket which can be added below (suggested) , or you simply bolt to your crankshaft using a washer and your harmonic balancer bolt.
