Correct flywheel for a 68 Z

[jims68z]

I need to purchase a flywheel for my 68Z.  Can anyone help me with a size and part number/casting number if there is one?  Is this the same as just about any small block chevy or is the Z something special?  Someone told me that the flywheel would even be the same as the one on a 6cyl motor.
