VEHICLE IDENTIFICATION NUMBER

IMPORTED MODELS - The vehicle identification number (car serial number) is on a plate welded to the body on the left front door hinge pillar.

This number is also stamped on the top surface of the crankcase, just forward of the valve lifter cover on the left side, and constitutes the legal engine number. Toward the right side of this same surface will appear the production code number, (stamped upside down from the front of the engine) this number, along with the vehicle identification number (car serial number) will be used to identify the engine on product reports etc. The production code number does not constitute a legal engine number for registrations, titles, etc. A stamped 1/4° long dash directly following the production code number indicates a production engine with .010° O.S. pistons (US production only).

The body serial number plate is mounted to the right of the air intake blister on the left hand side of the cowl.
