The top line denotes the week and month of production. Month codes begin in January with 1 and end in December with 12. The weeks are broken down as A= 1st week, B= 2nd week, C= 3rd week, D= 4th week, and E= 5th week.

Second line; ST is for style, 67 is the year, 13817 is the model, K is the assembly plant, 102845 is the sequential body number, BODY refers to the the assembly plant and body number

Third Line; TR is trim, 750 is the interior code, RR is body color, PAINT stands for the body color.

The next set of codes are by far the biggest headache of all. Just recently has these codes been given to the public, but trying to obtain a list of all of tham and them being correct is damn near impossible. I have what I believe is a pretty accurate list but these should only be taken at face value and not the gospel truth. I am working at finding the rest of the information and as soon as I can get my hands on it I will post it. The codes are broken down into 5 groups, denoted by a number. The first group has no number. Also there are some codes listed more than once in the same group that is becaus what has happened is that the code has been redesignated with another option. Also some codes are plant specific. I will get this list updated and fixed ASAP so that there will be little confusion. If there are any questions Email them to me and I will help you out.
