I just got a dealer quote for the tension rod $42.00x1, washers $7.00x2, bushing $19.00x2, collar $8.00x1 and nut $5.00x1, total :$107.00. These prices are from my local dealer. The tension rod was not in stock at the dealer.
I decided to by the comlete set from Courtesy Nissan, the complete tension rod with washers, bushings, collar and nut costed $79.00 which inludes shipping. Although, Courtesy Nissan did not have the parts in stock, they claimed that they will get the parts from the warehouse within two to three days. Hopefully, I will receive the parts later next week.
