REAR SUSPENSION

CAR IDENTIFICATION TR5 - TR6

Before ordering any parts for your TR sports car, it is essential that you have full details of the chassis number, engine number, body number, rear axle and gearbox numbers.

Number Locations

Commission/Chassis Number	The commission number on TR5-250 and early TR6 models were mounted on plates affixed to the top of the inner lefthand front wing. The plate included the commission number which could have a suffix 'L' or 'U' (1971 on) for lefthand drive models, and 'O' for overdrive. Paint & trim colour codes were also shown.
	Later TR6 models had the commission plate attached to the lefthand 'B' post, below the door shut plate.
Body Number	Two plates attached to the bulkhead were body numbers. One was fitted by the manufacturers of the body shell, the other by Triumph. These numbers are not required when ordering replacement parts.
Engine Number	The engine number was stamped onto a lip at the rear of the lefthand side of all engine blocks, just visible below the spark plug. The engine number is essential when ordering engine parts.
Gearbox Number	The gearbox number is stamped onto the casing just behind the clutch lever cross- haft box. On later US models the number was stamped above the starter motor bulge on the righthand side of the gearbox casing. Use this number when ordering gearbox parts.
Rear Axle Number	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.
