I need to replace my 2007 Grand Prix struts and while in there, new springs. It seems that no where I search, Monroe, GM or KYB, nobody sells the strut/spring assembly in a single assembly. Monroe sell the rear 2 and GM does likewise, But I can't find a complete front assembly all put together, ready to slip up there and tighten it down and head off to have the alignment done. Does anybody know what I'm looking for ? Thank you !
