I show it as designed by Dave Scott under Exner's managment and built by Ghia. But it was called a Plymouth, not a Chrysler, according to my source. The confusion may be the result of the body being so heavy (apparently Ghia used a lotta lead in its construction) that it had to be placed on a Chrysler New Yorker chassis, rather than the Plymouth base.
Take it for what it's worth.
