Bolt Size For Roof Rails On D3

[Mudaroo]

Hi there, I wonder if you can help me. Can you tell me the size of the bolts that fix the roof rails or roof rack to the the D3. Here in the UK they are are M6 . I have just bought a Trailmax roof rack from Australia and had it shipped to the UK. I'm building it now but the first problem I have come across is the roof fixings. The instructions state use the M8 holes already in the roof. In the UK they are M6 . Can you tell me what size the Australian ones are.

Many thanks
David

They are all M6.

In case you didn't know, the stud that they screw into can be unscrewed and replaced.
