Through-bolted with 1/2" or 3/8" washers. BTDT.
When i tried to install backing plates in some of those places, I ran into the problem that the underside is curved - e.g. the outer bolts actually come through a fillet at the edge of the deck, so there is no flat surface for a backing plate to bear on. I punted and at least stuck some fender washers in, where they would fit. Maybe a backing plate could be installed with a heaping pile of thickened epoxy filler?
