This might be a silly question but will it have no worries fitting a Aus spec 4 seater? Apart from the crack is there any other fixing that needs doing?
screw hole. On the right corner of the kit where the screw goes through to hold it onto the panel the side of the circle was chipped off (cant see it). Could put fiberglass and place it over that area then drill a new hole when you fix the crack... but dont think its needed as the car it was on just had a spacer underneath and it was fine. As for fitting it should be fine as far as i know its only the skirts which are different as far as i know when it comes to 2+0 2+2 etc.
You can see in the picture Look at the top left of the picture on the bodykit where the screw goes through to the panel.
Rear bar will also only fit a 2 seater, not a 2+2. Good luck with the sale, someone should pick this up soon!
