In 1967, the 442 was an option package (W29) rather than its own distinct model line, meaning it shares the 33867 Cutlass Supreme VIN sequence. Because your car was built at the Lansing plant ("M" in the VIN), with the cowl tag showing it is a factory 442, with the 5V code stamped near the bottom. Without this 5V code it would have been born a standard Cutlass Supreme.
The 5VM stamped on this cars Lansing cowl tag officially confirms that this car is a factory-born, authentic 1967 Oldsmobile 442 Convertible. The three letters break down as follows under GM group 5 accessory codes:
Group 5 Accessory Breakdown:
5: Indicates Group 5 options (always stamped at the very beginning of the option row).
V: 442 Performance Package (stamped only on genuine 442s built at the Lansing, MI plant).
M: Deluxe Rear Seat Belts.
Because the 442 was strictly an option package (W29) for the Cutlass Supreme in 1967, it did not have its own distinct VIN sequence. The 5V mark on the cowl tag is the holy grail for collectors because it serves as the ultimate factory proof that this particular car rolled off the assembly line as a high-performance 442 rather than a standard Cutlass.
This 442 convertible originally came equipped with the following upgrades:
A 400 cubic inch V8 engine producing 350 horsepower (Large "E" stamped right next to the oil fill tube/thermostat housing to verify if the original engine is still there).
Heavy-duty suspension (heavy-duty springs, shocks, and front/rear anti-sway bars).
Out of 10,897 Cutlass Supreme Convertibles built in 1967 only 3,080 were factory 442 Convertibles.
