What size socket due you need?
James O January 4, 2017
I dont have the exact measurements of the socket size needed for the job. Our parts are designed to be exact replacements for what came with the vehicle, so as long as your year, make, and model match up with our listing, these will definitely fit and function just like the original. If you have a basic socket set you should not have any problem matching it up, or taking it to an auto part/hardware store and matching it up there. Please let us know if you have any other questions.

The recommendation is for a 2003 Buick century but mine is a 2002? That’s what I typed into the search but this is what came up.
