i wouldn't expect to see rivets on the asf - as they were mainly used for
joining the body to the space frame.

'01 s8

At the NYIAS they had a display of the new A8's space frame.  I dont
recall seeing any rivets on it at all, but then again I cant say I
specifically looked either. I did notice threaded bosses that had torx
like bolts in them at certain joints.. maybe this is what they are
calling rivets?
