I had exactly the same experience, my new hull came with the new rudder installed, i also told the dealer that i was coming from a 2007, and so it came with the mast receiver for the "outtie" mast. so all I had to do was move over the akas and I was good to go. You'll likely get a new pin for the mirage drive as well, it has squared off ends rather than the tapered ends of the old style. I didn't bother putting that in until I was servicing the drive, didn't have any issues.
Thank you for your immediate reply. So now I am just waiting for it to arrive and I hope for these parts to be included in the delivery.
