Long story short, rough driving lead me to bending the right rear upper control arm on my 2005 C230 K.

I put it on the rack and tried to align it, after noticing the steering wheel off center and the right rear wheel showing some serious negative camber. Unfortunatly when I saw there is no camber adjustment I quickly noticed the control arm.

My problem is, I'm used to working on Honda's all day so when I ran into this I was a little thrown off. I already have the parts but I'm having some difficulty locating, but more so putting a name to the tool I need to remove the control arm itself. The bolt looks like it needs a rather large double hex/ or 12 pt torx. The Snap-On truck shows up Monday but I haven't a clue the exact name of the driver I need. Is this maybe a special tool?

The picture attached is that of the lower steering linkage, but the bolt is the same



Thanks for your time!

 

Ok, well I figured its a triple square, not sure on what size though
