There was a thread about a year ago that someone was interested in Z-11s. I couldn't find it in a search. Anyway, there is a good article in the new Hemming's Musclecar mag on Don Fezzel, the owner of several of the remaining Z-11s.
I think it was JC, glad you saw it. Don Fezzel is here in Pa., goes to York US 30 reunion all the time.
