Hi Rob,
I think the posts you are referring to were about Ash G,s IVA test, where he was told he needed 2 fixing bolts,
I,m not 100% sure if it is stipulated in the IVA manual for the number of bolts needed, maybe its another "depends on each individual tester,s opinion".
My own back stays go right down to the bottom of the chassis as I,m using a GRP rear tub which has a different rear framework than the book spec one, so I used 2 roll bar mounting plates ( same as on the upper mounting points), welded in a 3mm plate to the chassis & bolted the lower back stays to that plate with 4 bolts on each side, so there is 16 bolts securing my roll bar , seems very strong & also allows me to remove the roll bar if needed etc.
cheers
andy
