How was it cut out, did they just chop it off next to the bottom attaching bars with a torch? to start with, I would take measurements. Start with your car. As the cage needs to fit within, measure under the car rocker panel inside to inside, both front and back,as the cage / frame will be welded to them. Then inside the car roof to lowest floor area behind the seat where the hoop would be located. That would be a start to see if it is even close.
