I ordered the wrong size barrel nuts originally and JA racing were extremely helpful in not only excepting the return but also cut the unique size that I did need which is not widely available on the net or in local hardwares.My roof box was being held on by three barrell nuts rather than four. J a racing ensured I now can drive safely knowing my roof box is connected to my roof rack safely.Thanks James and team

Brilliant
