2001 Mixed 1999

Are there any mayor diferences between the rear clip of a SlK230 2001 and a 1999?. I am about to buy a 2001 with rear end damage and I found a 1999 rear clip to fix it but I am not sure if these two match.

Check with your local used parts dealer/junkyard. They often have a cross reference for what years will match up for different parts.
