What is the correct spacing for a 91 caprice classic upper control arm?

it broke one of the bolts and i didnt find any spacers like the other bolt has in the arm. i do not want to put it in wrong and test drive it if i can do it correct the first go around. quick show of the space of the holding bolt a href="http://www.youtube.com/watch?v=EOJ4zT0iT8o...." rel="nofollow"http://www.youtube.com/watch?v=EOJ4zT0iT…/a thanks much!!!
