If you take the black spacer out, the smaller round aluminum standoffs can tear through a fiberglass floor fairly easily if there are no larger flat plates to spread the seat loading over a greater area. The larger protective spacers do not need to be very thick, 3/16" to ¼" thick and maybe 2 or 3 inches in diameter with one on each side of the floor to do a better job of protecting your fiberglass flooring.
p.s. Use a reasonably thick flat sheet of medium durometer rubber or a similar diameter thick rubber washer between the protective spacers and the fiberglass floor with some type of locking nut. You want to be careful not to tighten the fastener as if it was a head bolt. If you do, you will crush the fiberglass even with the rubber washers in place. At the same time you don't want your seat fasteners to loosen up while you are driving hence the lock nut suggestion.
