I emailed the AutoWorld people about this very idea and got an email back saying they would consider it. My exact request was to redo chassis plates to reflect a more accurate rendition of one without molded on exhausts, suspensions, etcetera. A kind of modular chassis that would say fit a GTO as well as a Chevelle, Olds, Buick, and a series for a lot of the Ford Mustang and Falcon based platforms. This would work for various Mopars as well.
