Rollbar?

[chriseyj]

Hi I read the concerns with IVA and the roll bar stays requiring 2 fixing bolts each when the roll bar is used as a seat belt anchorage.
Therefore when I made my stays I welded 2 spare suspension brackets to the lower cross members (GRP TUB) either side of the fuel tank.
I then welded a crush tube into bottom of stays and have clamped them wih an M12 bolt.
Now I'm worried because its actually only 1 x m12 bolt either side but it clamps through 2 holes in a suspension bracket.
Also the bolt would have to shear in to places for the stay to pull out, unless it shears and the the bolt falls out?
Wondering if to add anothe form of fixing for security.

Thanks Chris
