Albert....the main reason for mounting them there was the fact that I would have two thicknesses of fibreglas for support hence a much stronger place to mount them.
yesterday I got around to reinforcing my seat mounting points.....my initial thoughts were the flat bar that I used would be strong enough, but after having a read of the IVA manual I was not so sure, so I opted for beefing up the floor with some 3mm ally, top and bottom so now the bolts go through 9mm of ally and 6mm of steel

.....I am fairly sure that will be enough
