67 to 74 disc brake conversion, PLEASE HELP!!!

Thank you for all the comments, I am not sure how to get the alignment because the grinding is so bad I am a little nervous to drive the car, I knew after the project that I would need an alignment but didnt expect that it would be needed that bad lol, I spoke with the company that sold me the conversion kit and he told me to purchase a upper control arm from a 76 aspen and I looked at the control arm from the aspen and it looks nothing like what I need.
