Depending on the brand, I believe that new end links typically come with new fasteners. at least the budget ones that I put on my cobalt did. (AOD tech)Replacing my End Links with a sway bar upgrade, i have two nuts but two are going to have to be cut off, i was also told they all need to just be replaced anyways. Honda is Cheap and the OEM ones don't come with nuts, so im going to buy some 14mm Nylon Locking Flange Nuts From Amazon, But i need to know what thread size i need? i was told it might be M10? But Hondas website doesn't say, the generic Overpriced sold as Made for Honda End Links Nuts Don't say, so does anyone know?
