96 STS Rear strut replacement

I ordered new monroe struts for the rear of my '96STS (advance auto parts #40046). The more I read about the suspension on these cars the more worried I become! Here is the link to the struts I ordered

They say they are an exact fit for the 96 STS, with air leveling system, but without electronic suspension.

Does my STS have electronic suspension? or just auto air leveling? Any thoughts or comments will help. Love the car but don't want to dole out the $ for OEM struts.
