I just received my copy of Collectible Automobile (Feb. 2008). There is a great interview with a designer by the name of Bob Marcks. He started out at Ford but then left and went with Loewy and worked with Bob Bourke on the 53 Studebaker. He went back to Ford but then left again and started his own design firm. He was hired by Studebaker do the 66 model.
He did several designs for future Studebakers, including raising the rear bumper on the 66. He proposed a design with a front end similar to the 53 and one with a similar rear window like the 47-53 Starlight coupes, but, as we all know, there would be no more Studebakers.
He later joined Chrysler in 1973 and worked on the Cordoba and Dodge Magnum and other Chrysler products.
