Can someone confirm this?

I want to press out and press in my ball joints. And know it can be done and will be done. I wanted to confirm if I can even do it. I was looking for the part # for the control arms and find only one Set of numbers. The number on the right side was

466

09 CDP

written that way.

I have an m3. Do I have the right control arms? I feel something's "off".

Can someone confirm this?
