I presume it is a Burman box in your 72?

Oil leak is usually from the lower oil seal where the Pitman arm is.

Filler plug (it is in fact not really obvious, tbh!), oil weight etc, see here:
Burman Box #1

When you remove the filler plug, check if it is vented......there was a Technical Services Bulletin from Alfa issued, that recommended to drill a small hole in the side of the filler plug to vent the box, as the burman box lacks venting and led to leaking, for which see Papajam's post here:
Alfa Romeo Bulletin Board & Forums - View Single Post - Steering box leak

Still can't see where the refiller is?

Has anyone done this recently and can advise? Thanks

got a photo of the top of the steering box?

I had a drive in another spider yesterday, thanks Matt, and the steering was much lighter, despite having wider tyres. Will upload a photo of the steering box, not sure how to access it as it is buried beneath carbs.
