There were three different styles of interior available in 65 442s.  Well, four if you count the bench seat option available in Sports Coupes.  Below are the styles and colors used in all four body styles.

Holiday Coupe (3837) and Convertible (3867) use the same seat and door patterns.  Rear seat in convertible is narrower to accomodate the top mechanism.
