The stock tire carrier on this D90 met its unfortunate demise after a run-in with a Jeep (the Defender easily won the battle, but the tire carrier was sacrificed). However, this was a great opportunity to upgrade to the Safari Gard carrier.
UPDATE: This upgrade occurred during the short-lived revival of Safari Gard by new ownership, circa early 2008. Since that time, it looks like Safari Gard has once again faded away. The revival was good while it lasted: this tire carrier came in a week after ordering it and the quality is simply fantastic.
