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. Wherever possible we have listed part applications by car number (c).
In some cases, we had to use the engine numbers (e) or the body numbers (b). Commission numbers, as used from I968, are of little significance and are not used for reference purposes. Where we use years, they are model years, not build dates.
