Hi darrel I've got my max tracks bolted to them and we usually put the kids pram or bike on it other blokes has done the same and said they hold a bit of weight
So the first pic is how the back rack is bolted
The second pic there is a hole in the frame is where the front is bolted but I made a mistake and didn't allow for the feet of the racks that's why I had to drill through the frame and the last pic is of the rock armour max tracks that was nut serted in the frame. The roof racks were from a Nissan pintara
