8 pin BB tool?
 

I never needed an 8 pin tool so when I ran across this, I confidently ordered the only 8 pin tool I saw. As you can see it's way too big. Other than trying a shrinking ray where can I get the correct tool for this simple job. I saw a Campy tool that looks possible but I'd like to be sure. Guys, please help me out. What do I need and where's the best place to look? Thanks in advance.

as you can see the bb18 doesn't quite fit. It's a '85 'dale st500

In a pinch an adjustable pin spanner will work.
