well honestly i dont see why you would need new hinges, unless they have wallowed the holes out from hanging so long.. this was aggravating but straight forward and i only spent 15$ on the hinge kit from oreillys. i was all for this being quick and easy until i realized i was gonna have to grind the old pins out. youre right about the wind noise.. i let mine get so bad that when i would hit a good bump on the interstate it would chop like a back window was cracked open lol..
