A build sheet in the traditional Chevelle/A-body format is very unlikely in a Lansing Michigan built 442. The broad cast card will have some pertinent info and confirm the W-30 status of a Coupe. The good news is that other types of factory documentation, such as line sheets and/or inspection sheets have also been found.

Under the rear seat, behind the bucket seat back and under the drivers foot well carpeting are some of the most common places to find the broadcast card.
