What car takes a 72 inch driveshaft?

There's no single car that definitively uses a 72-inch driveshaft. Driveshaft length is highly dependent on the wheelbase and drivetrain configuration of a specific vehicle, and even within a single model year, variations can exist based on options (like different bed lengths on a pickup truck).

A 72-inch driveshaft would be exceptionally long, suggesting a very long wheelbase vehicle, likely a heavy-duty truck, or a custom application. You'd need to specify the *make, model, and year* of a vehicle to find out if it uses a driveshaft of that length. Even then, you'd likely need to consult a parts diagram or a specialist.
