Front strut part numbers issue.
 

So I got some used front struts for my Koni insert project and they both have a nice clean label 987 343 031 15. But when I look on the Automobile Atlanta online parts diagram I see 987 343 047 02. Which is correct for first gen. Cayman S? I did confirm the correct spring color codes however.

I did find the 987 343 047 02 stamped into the bottom of the strut tube. Perhaps the paper label is from a used parts vendor selling the strut complete assembly. Anyway, it looks like the correct part.
