Modifications are a continuing and unpublicised process in vehicle manufacture.

Spare parts manuals and lists are compiled on a numerical basis, the individual vehicle numbers being essential to identify correctly the component required.

The vehicle identification plate is located on the right-hand front wing valance in the engine compartment (see illustration).

Vehicle identification plate (1) and body serial number (2)

The body serial number is stamped on the scuttle crossmember above the vehicle identification plate.

The engine number is situated on the cylinder block. On non-XU engine models with an aluminium cylinder block, the number is stamped on a plate which is riveted to the flywheel end of the block; on later models with a cast-iron block, the number is stamped on a machined surface on the flywheel end of the block. On early XU engine models, the number is stamped on a plate which is riveted to the timing belt end of the front of the cylinder block; on later models, the number is stamped on a machined surface at the flywheel end of the front of the block.
