Unfortunately, The Replacement Hardware Kit # RHK will not include the bracket that appears in the image for Curt Hitch # 13554. I contacted Curt and they do not sell the bracket alone. You will have to repurchase the entire hitch to be able to get the bracket.
I attached an installation link below for The Curt Trailer hitch being installed onto a 2010 Infiniti FX35. It will be the same installation process for your 2009 Infiniti FX35. If you have any further questions please reach back... view full answer...
