Almost identical in layout to the Miller I had.
I wish I would have documented that project a lot more. Basically I glassed in some cut down 2" X 4"'s to the floor. Then screwed the seats down to the 2" X 4"'s, screws went through the seat bases (the part you see when the seat's bottom cushion's are out. Screw's were of the regular drywall type of screw. I also shot a couple of screws in through the side of the seats to the side of the hull, but that didn't need to be done.
The only pic I could find of those 2 X 4's, not sure if this pic is before they were replaced or after.
