Austin Healey Vehicle Identification
When ordering parts, it is essential that your car is identified exactly, by model year and serial number. Since many part changes were made during model years, the car number, engine number and body number provide the only positive identification. Quite often a car’s title will not show the correct model year. Before ordering parts, please use the space provided below to copy the applicable numbers from your car. Use of these numbers is the best way to insure that you order and receive the correct parts Wherever possible, we have listed part applications by car number(c). In some cases, we had to use the engine numbers(e) or body numbers (b).

The Engine Number is stamped on a plate secured to the front left-hand side of the cylinder block. (100-6 and 3000 only.) The 100-4 is numbered on the right-hand side of the block.
The Gearbox Number is stamped on the right-hand side of the gearbox below the oil level dipstick (except BN1).
The Car Number (A) and the Body Number (B) are stamped on plates on the right-hand side of the firewall.
