I am putting a new manual steering box into my 67 Coronet. I know the pitman arm can only go on the box one way, but at what position do you put it through the center link? Years ago I turned the wheels all the way one way and then the box all the way that way and then hooked it up. This did not work though as it was about a 60/40 turn ratio rather than a 50/50. Thanks.
