Triumph TR6 Vehicle Information



Location of Serial Numbers
Before ordering any parts, it is essential that you have full details of the chassis number, engine number, body number, rear axle and gearbox numbers.

A. The commission or chassis number on early TR6 models was mounted on plates affixed to the top of the inner left hand front wing. The plate included the commission number which could have a suffix “L” OR “U” (1971 on) for left hand drive models, and “O” for overdrive.

B. Later TR6 models had the commission plate attached to the left hand ‘B’ post, below the door shut plate.

C. Two plates attached to the bulkhead were body numbers. One was fitted by the manufacturers of the bodyshell, the other by Triumph. These numbers are not required when ordering replacement parts.

D. The engine number was stamped onto a lip at the rear of the left hand side of all engine blocks, just visible below the spark plug. The engine number is essential when ordering engine parts.

E. The gearbox number is stamped onto the casing just behind the clutch lever crosshaft box. On later USA models the number was stamped above the starter motor bulge on the right hand side of the gearbox casing. Use this number when ordering gearbox parts.

F. The rear axle number is located at the base of the axle housing, when viewed from beneath the car. Use this number when ordering axle parts.

IMPORTANT NOTE: Vehicle Commission Numbers & Component Serial Numbers. Wherever identification numbers are quoted in this catalogue (to help you to distinguish Factory changes/years), they relate to the Original Factory Specification or Component(s) when the vehicle was new and not subsequent or miscellaneous replacements.
