I mentioned the spreadsheet I started for my March built, 403 SPD 1970 Valiant. Here is a list of some of the date coded items these cars can have. Obviously, some will not apply to an AAR. (AC as one example)

This list was compiled with help from Scott Smith, Dan Pausch, Kent Johnston, Ola Nilsson, Robert Schirmer & Grant Piche.

You can enter the relevant data into a spread sheet for your AAR if you choose to.

You may also find date codes on other parts to add in as you go.
