The model # and size is cast into the center of the wheels by the lugs, the ET is stamped there also.

He's just giving you crap because you did not need to thread jack this thread for your personal requests for wheels.
OBVIOUSLY there are enough FS threads for BBS's that you really did not need to post here and as a member since 05, you really should have known better.
Now, once you get the wheels, please feel free to post a pic.
