I was worried about fitting the Thule roof bars onto my new Trafic as the instruction called for the help of an approved body shop and the removal of the headling
Anyway after some further digging (as it seemed a little extreme as after I'd found the step-ladders and clambered on up there, there seemed to be some lovely brackets already in place...).
Anyway I now have the CORRECT brackets coming tomorrow which are bolt on..
So if anyone needs the info;
Renault Trafic SWB Low roof 2006 model year
Thule roof bars rectangular (Aero don't go large enough) 1500mmm +
Feet part number 751
Adapter part number 3009
With this system all the usual Thule accesories will fit, ski carriers, boat, board, cycle, boxes etc.
Hope this helps...
I found these guys the cheapest
