There was evidence that one of the bolts holding the steering arm had been
cracked for a while, although it might just have been a rough weekend at
Blackhawk (before they repaved).

Subject: RE: Grade 8 Bolts In Suspensions
If I understand the description of Red Rat's failure, it was a steering arm
that let go. Loads on this part would put the fastener in tension,
and thus a grade 8 would be appropriate. The hardware used at the corners
of the A-arm and upper trunion are soft as those components subject the
fastener to shear loads.
My opinion without credentials.......
