Steering leak ?

 
Just about to do an oil change and noticed this big bolt is dripping wet. Looks like oil, but as it’s below the steering box, I’m assuming it’s leaking. I’ll investigate further at the weekend.

Just doing mine too… on mine it’s the right angled pipe shown at the bottom of this photo -

 

(so on the top of the steering box on the car)



 

Looks like mine is leaking from the bottom as it’s dry everywhere else. I assume it’s just the 3 bolts to remove it.
Anyone doing a rebuild kit or exchange service of these ?

I haven't found any such service. Or a video or how-to service the box other than for other makes or more general. Seems that it is not possible or profitable.
Please correct me if I am wrong!

So I'm just getting round to taking this off the car to be sent away for refurbishment but have hit a stumbling block. 
Seems I can't get 2 of the mounting bolts off without taking off the radiator mounting brackets. Is the bracket an easy remove ? I've removed  one bolt which was a bit awkward and I can see another one before it got dark and started raining. Does this sound right ? I was hoping to get it sent this weekend. 
Thanks. 

I had my radiator out when I changed the engine. No hassle as I can remember. Two bolts each side and maybe a bracket for pipes and the clutch wire. 

Will you get the the worm gear changed as well?
My box got so much play now. Worn out.
