That is my toy and I remember meeting you at the Glenn that day.
You may want to call Jack Barsh at Full Throttle Powerboats and ask him to keep an eye out for a Grandsport for you. He sees probably a dozen Allisons per month in for cosmetic repairs [mine will be there next week] and he is actually building new XR02s from the original molds he has there.
He was finishing an absolutely beautiful XR02 that was Bahama Blue/white when I was there yesterday. He can even build you a carbon/Kevlar XR if he can find time. You need to stop by his shop which looks like a catalog of every high performance boat ever built.
