Thanks for the tire chart.
Donnie,
I think that it's all but standard practice for the floor to have "core mat" in the floor panel, which is quite stout. N&N says, "We use a core mat in the roof, doors, trunk, and floor." On the '32 roadster I'm working on I've made up four 1/8"x4" panels in various lengths with 3/8" Grade 8 bolts up through the floor, tacked to the bottom side of the plates, each catching two of the eight seat bolts (buckets) - one on each outside pair running front to back, one in front catching those bolts on both seats and another in back catching the two inner back. The plates will be epoxy primed, then stuck to the bottom of the floor with some body filler as "glue", and finished along with the bottom of the body, likely with a bed liner material again as I'm on a gravel road. For a seat to come out it will have to take most, if not all of the floor out with it, which means likely taking the whole body. Another option, even stronger, would be to take a sheet of 1/8" steel that covers the bottom of the floor, and weld your bolts to that, bonding it to the bottom side, but as you say a fiberglass body is going to tend to break up in a severe impact....
