I have a 2002 Deville DTS with a blown right rear shock. I am in need of a used shock for the electronic leveling system. I am not sure what years will work but I think any 2000-2005 Deville shock will work as long as it is part of the electronic leveling system. I don't want to convert to an aftermarket system. Call me if you have one at (six-o-0ne)56nine-95ninety. Thank you.
