1 Prepare reinforcements (2) as per drawings.

 The reinforcements may be longer, but not shorter, in addition they may not project beyond the flange width. The reinforcements must not make contact in the U-section and may have clearance on one or both sides.

2 Bolt reinforcements (2) onto longitudinal frame member (1).

 Where possible, use the existing hole pattern
