Thank you for your help. I bought the kit and it had 4 ball seats which confused me. Your response was very helpful. You reference a drawing but I don't know how to pull it up, nor have I figured out how to access 3rd party hosting in photo bucket.
I would like to post a photo but I don't know how to do that yet either.
My next question will be about the Ross steering box. I opened the box, cleaned out all the grease, removed the zerk fitting, and have a plug for the filler hole. Now that it is all cleaned out, it appears that there is a ball bearing missing. Or should there be a gap about the size of one ball bearing in the race?
