Starbird was the custom car consultant for Monogram starting in 1961. Initially, Darryl offered custom restyling touches for a couple kits then in production, and continuing in the future for kits that replicated Starbird-built/constructed cars. After two very successful years of work with Monogram, Monogram exec Bob Reder contacted Starbird in 1963 and offered the buy the Predicta and suggested that the car should be mildly be restyled and freshened so that the pending model kit would match the car. To fit the times, Starbird restyled the car, and repainted the car candy red in which color Monogram molded the kit.

However, before and after the Monogram-triggered changes, Starbird has continued to make refinements to the car. Here's a brief introduction of the many changes that Starbird made to the car:
