Almost forgot your other question:
Elenor was a 1-off car. It wasn't a mustang with a widely available kit or aftermarket parts.
Having said that, TCP (Total Control Products) now offers an Elenor kit because of the demand the movie GISS created. I don't know how correct it is, but I do know they arn't chargeing nickles for a kit. Check out their webpage for more info.
