It's a kit from A.R.T. for a 69 Dart. The only place the body is attached is to the frame at the rocker panels at both the front rear crossmember, the front crossmember where the front frame section meets it (this will get cut in the center for transmission clearance) and at the very rear of the car at the tail panel along the bottom edge above the valance panel. The package shelf is still in the car and will stay there to support the roof pillars but I don't foresee needing any additional attachment points. It's pretty sturdy as it is.
