Help with a few RPO codes

[Company Man]

I am new to the GN family and have been decoding the 76 codes on the factory sticker in the trunk area of my 1987 GN.
I have had good success but seems that I have hit a road block on a few of the codes.
Hoping someone can help.

Here is another great site for your trunk sticker codes info and click home for many other great info to read:

I too was trying to make sense and found GM made a typo error on one of the code
My code is listed as 6YY were it should be 6YX.
Enjoy

Thank you, that helped and now understand what each one of the codes is referencing.
