Mackay and his crew built the cutaway car on the earliest Corvette chassis known, #003. The chassis was discovered in the mid-1970s when Phil Havens found it under the body of a 1955 Corvette he was restoring.
The #003 car was used for durability testing, including a punishing 5,000-mile test over Belgium Blocks. Chevrolet Engineering Department Work Order, #19013-27, issued on Aug. 20, 1953, instructed that the frame be changed. So it survived.
Sam Folz, president of the National Corvette Restorers Society (NCRS), identified the chassis as 003 and confirmed it as the oldest Corvette chassis known to exist.
For the ’53 cutaway, Mackay used the body of a 1954 Corvette parts car. He summed up the work that came next: “It took a tremendous amount of designing, researching, documenting, hunting, measuring, cutting, bending, splicing, and engineering.”
Mackay left the windshield and grille intact, and then he made “floating” elements: the left-side headlight, taillight, fender emblem, body side molding, horn, armrest, and ashtray. “It looks really cool displayed at dusk, with one headlight and taillight floating in air,” he said.

A couple of years ago, he found an L88 1969 Corvette at a machine shop and did something similar to showcase the work he and his Valley Stream, NY are famous for
