Bolt for steeda ta and underdrive Pulley

[MGSTANG]

When you install the underdrive pulley and timing adjuster, do you still use the stock crank bolt even though you are adding something to the front of the pulley. Is there enough threads to use the stock length bolt?

not needed their is enough treads.
