67-73 Abody frame Rail and Rad Support

Hello - Great video and thanks for putting it out. I have a 66 Barracuda, same frame rail issue on the driver side. 3 Questions. What kind of welder should I be using for a job of this nature, 2 Is AMD the best place to purchase the frame rail, 3 Where should I get the front-end frame measurements from?
AMD only makes rear rails for A bodies. If they did make them they would be 67+ variety and wouldnt work for your 66. You will need to find a donor from an original car.
