Leaking oil from steering column

[JDGreenThumb]

I have a JD 755. Noticed a leak trickling down the steering column from the steering wheel. Looked for an exploded view of steering box and column to see what seal or seals may be involved but have not found anything helpful as of this posting. Any input as to what seal or seals I need to replace or is this something that may involve a complete rebuild of the steering box?

I am thinking item 8 which is the steering column seal kit part AM107078
