Hey, I bought my 06 ss/sc used (see sig), the previous owner did some modifications to it already, CB and cross drilled/slotted rotors, and I'm wondering if theres anyway to double check and make sure the steering knuckles on the car are the stock ones and haven't been upgraded already.

thanks for any help.

 

Look for a stamped part number.

 

Bleh, now I feel foolish. That makes way too much sense for me to think of, thanks for the help heh.
