Correct me if this is wrong, but aren't these wagons built on the longer Fleetwood Sixty Special chassis, rather than the Series 62 platform? I believe Doris Day had one of the Woody '56's. If you want to try to find the fellow in Dayton I mentioned above, he is the brother of Mike Turner, who was Mayor of Dayton, and later a congressman. The wife of the guru has the unusual 1st name of "Kennedith," usually shortened to "Kenny," but I can not recall his name. If you know any Cadillac Club folks, ask around there. Someone will know.
As an aside, I have Willard Hess' autograph in my "Black Book" that MacP wrote ages ago. I met Willard at a Cad Club meet in Cincy in the early '90's. We were chatting next to my '72 Cad Formal Limo when a t-storm blew in, so we dove into the rear of the Fleetwood, where for the next hour he spun tale after tale about the business. Great old guy. And, he confirmed the story about the early '60s T-Bird that was alleged to have been fitted by H&E with a windshield ground to the customer's eyeglasses rx. They really did do that. Had to use flat glass, not curved, but they pulled it off.
