I know this post is old but just came across it. All of the cars were factory fastbacks 1 6cyl 2 with 289 and one 390 . My shop sourced and built all 4 cars in 30 days for the movie . The cars were ruff cars but still a shame to have used them for this. All of the fiberglass came from Branda .3 of the cars were powered by 302 engines and the 4 car was a cut away with no engine. If you look at this car and even on the movie you will see my sticker on the trunk lid. It took a crew of about 6 guys working around the clock to make it happen. All of the cars made it threw the movie with mostly sheet metal damage. As for the one that supposedly had a coupe vin unless it was changed after movie or a factory miss stamp it's just not true . The movie company may have sold them without titles and now it has one.
