I was contemplating beforehand whether I should post on this forum as I expected some reaction.
Floors are bonded with Fusor panel adhesive. The screws you see are stainless m4 flanged button heads used for clamping. and are now seam sealed. New rails were attached with Mig plug welds.
I have been following your build with interest, good work. At the moment I actually work in Canberra in the week and commute back to Brisbane weekends.
Its 2017 and technology has moved on. 3M and Fusor Panel adhesives are used to bond roofs, floors, quarter panels etc in most new production vehicles. Often stronger than welds in tests.
I build this car last year.

In this case the entire floor (a carbon fibre composite sandwich) is bonded to the space frame with structural epoxy. The frame and floor was then subjected to a beam and torsion test as required by the ADR's for compliance and passed with ease.
