Rani, I fabricated the frame connectors myself, from what started out as 3" X 2" heavy wall tubing, cutting them to the shape of the floor pan ( just like the boughten ones) I tacked them in place with the car sitting on its wheels ( full weight) and then later, when I disassembled the car, and mounted it on the rotesseri, I rolled it upside down and welded them in fully. then the bottom of the car was primed/ painted, on the rotesseri.
