Anywhere that gives a guide on installing the OEM Mini roof rack for an R53?

 

I'm not sure if there is a how to, but I think that octaneguy has some article about it, do a google search it should come up or look por the part number on realoem and then do the search if I find it ill get back with the info.
From what I understand its PITA and risky to do and any mistake will require PDR to fix or worse
