Installed my brace and set upper back seat in locked in upper hook and bolted bottom back in. The back brace bolts on the truss behind it. It will have bolts welded to it that slide in to the truss and bolt in. I could use the floor but these are reachable as well. Bottom put I can slip hand in and put but on. Pretty simple very straightforward and the sides fit great and will cover the wheel well. I could put a black piece of carpet on those but seats have a boltster on each side.
No picture but at bottom on back is a 1.5 wide piece 1/8 thick metal piece that bolts to back of seat in existing holes you can see the nuts when installed ticked inside seat frame. The bolts will stick out back of frame different location into the truss and through the back seat material when installed. They already were checked with cushions prior.
