hi all, i recently started using my base model outlander 2007 for work and wanted some roof rails fitted, now ive bought some without researching and seem to have wasted my time.. but im not sure. picked them up from a breakers yard and theyd already been removed, one side has 2 brackets missing which i didnt realise till it was too late, but the other side i have looked at fitting and the brackets dont seem to line up with the ones already on the roof.. am i missing something here, are the roof rails of different sizes for models that dont come with factory fitted rails.

any help is appreciated

thanks dean
