hi Rhys, I fixed my post as it was not showing the first pic. I can take some others with more detail if you want.
yup, it bolts through the floor with 3 bolt plates.
It was pretty straight forward except for the drivers side front leg plate. My esky has the factory reinforcement? plate, which the bond supplied one did not fit. I ended up putting in some crush tubes for two of the holes and had a piece of tube welded in for the outermost bolt. probably not cams legal, but I'll cross that bridge later. The other tricky part was cutting the rear bars to the correct length.
If I had to do it again, I would place the rear legs higher on the wheel arch to increase the angles of the cage and harness bar. Also, As I am quite lanky, I had to place the main hoop a fair way rearwards, this meant that the front legs are not as close to the front of the doors as I would of liked
