|To decode your car's trim code (found on the metal tag on the driver side door), look at these trim charts from 1974, 1976 and 1978.
The first number in the trim code is the last digit of the model year (i.e. 4=1974). The next two numbers are the color designation, found at the top of the chart. The last letter is the seat and fabric style designator. Follow the color designation on the chart down, and locate the letter code under that color that matches the last digit in the trim code, cross-referenced with your car's body style, indicated in the far left column.
