hey guys new to the site hello all. ok my question... i have a 2008 grand marquis and i trailer with it (ive had mutable police interceptors in the past) which i know have stiffer suspensions.. anyways i want to put aftermarket coils on the back(not for height but for stiffness...) i cant seem to find any springs what so ever for the 2008 but i can find 2006 are they compatible? if so does anyone know a site where i can find them? if anyone could help that would be awesome..

I also have problems with what works on what. I found this with a search,

http://www.mypartshop.com/default.aspx

site uses Hollander data base and may be just what we are looking for. Doesn't necessarily have the part, but may give insight of interchange years.

Good luck, bob

In terms of rear suspension, I am pretty sure that 2003 - 2008 are interchangeable.
