I threaded on the jamb nut, with weldable bung and measured the distance between where the tie rods should be. I then tacked it together and made sure I could get my toe in right. Once that was done I finished welded the bungs. That is another whole process, weld 1/4 at a time opposite sides and let it cool so you do not weld through. There is a better write up on here somewhere.
