2000 and 2001 passenger side aie bag
 

Whats different between the 2 on a 2000 and 2001 s40 passenger side air bag. The dashpad is the same

Searching for used parts at this site suggests there is a change after VIN 600204 in the 2001 model year. Searching for the 2000 year though turned up nothing.

I have not researched anything to know if this is correct information.
