<VV> front sway bar hardware

[John Kepler]

I know the local h-store has regular, grade 5 and stainless hardware. Grade
8 might be a stretch for the local h-store? Is stainless just as strong as
Grade 8? 

WARNING!  First, NO stainless fastener is a "Grade 8", since the alloy is
specific to the grade-standard.  Second, most of what is sold as "stainless"
fasteners will not pass an SAE Grade 3 standard yield-test, let alone a
higher standard!  It is the LAST fastener you'd want to use on ANY
suspension component!

Does all the hardware need to be Grade 8 or just the long bolts that go
through the lower control arm?

I wouldn't use ANYTHING but an SAE 8 on ANY suspension part!
