Hi guys I have a 58 3600 4 on the floor. My steering is somewhat loosy goosy 1.I would like to firm it up a bit if possible. Thought I would start by adding oil. There is 4 sided bolt on the top of the steering box. Can I assume this is the fill plug and there is no drain plug. 2. I have heard ther is an adjustment you can do with a screw and lock nut, Can anyone elaborate on that
Thanks Rick
