is there a cørrect position for the headlight mounting bar for and aft in relation to the centre line of the front hubs,
cheers.

Near enough so the wheel doesn't clout the lamp bracket on full lock. Pair or grips and a friend should sort it - Check for height (should be fine) and visibility from front (Both SVA issues - Useful picture in the 'unofficial' manual available on-line with a quick search...)
