He just replied to me......
@rwdisgreaterthanfwd I have re-confirmed with the owner. He represented it accurately in the video as "a frankenstein" of parts, including all the trim, body pieces, and interior parts you're probably talking about to "prove" it's a Datsun. There are Datsun trim pieces integrated into the car. He also re-confirmed that it is powered by a Ferrari V12, with the suspension, chassis, and driveline of a Ferrari.
