sawzall dismantling

My brothers cut the skin off of a Mirada with a sawzall, left all of the inner structure, door frames etc(used the skin for a stock car), still had the slant six in it, drove it around the yard. I cut a 73 Chevele apart with a sawzall. Took all bolt off parts off, all I wanted was the frame for a racecar. I cut the skin off of a 86 Charger with a body saw, all that was left was the inner structure and roof skin.
