'99 Fairing lower bolt set-out question.

[Katana2]

OK. While we were at Bathurst on Satruday, up on the Mountain we saw 9/99 R/B number 537 (not a forum member, but we nudged him in this direction, F#$'n clean stock '99 by the way). That's only 5 bikes away from B1's 9/99 R/B number 542. B1's has the circular bracket (not a fabricated item) and 537 only had the one lower fairing bolt so must have been the straight bracket underneath the fairing halves!
