I actually discussed Dick Avery's role in the Datsun 240Z design with him personally, and it is true. Here is a thread about Raymond Lowey, the designer of the Avanti, and also info about Dick and the 240 design. Yes, it was done while he was at Ford.

Didier, you are now the proud owner of two Avery designs, one automotive and one marine!
