Build codes
I know this topic has been discussed over the years across the product lines. But, I need help. I got lost looking at the posts.
My 1981 928 is missing it's build/option code sticker(s). I have the COA and verified the information on 928oc (yes, I am a member). But, everything I am finding in my research is for option codes, not the mundane build codes.
For example, my shark is a 5-speed manual (code # M481). The COA does not show this as this was most likely a build code not an option code.
Also, I may have the 'Competition package' option (seats, shocks, spoilers and what-not) but not as an option (meaning it was a build code not an option for this car. My COA shows option # M471 which decode as "Integrated Rear Spoiler (87-89)". Yet, I have a 1981, not an 87-89.
I definitely have the leather dash/door panel/leather seat front & sides but not shown on the COA.
I guess my basic question is: How does one find the build codes without having the sticker(s). I do have the original owner's manual but alias, no sticker.
Any help is appreciated.
Thanks in advance.

M471 is Sport group 1 meaning Competition group. Same option numbers were used for different meanings on different MY.
