     Roger Garnett replied to my earlier posting of what
     left to do to Redcar, concerning the upgrading of roll
     bar/cage mounting bolts, with the following bit of
     wisdom; That roll bar mounting bolts should be grade
     5, as grade 8 bolts are more brittle and thus more
     likely to snap in the event of a rollover. Makes sense,
     has anyone else heard this ?

          thanks-
