As I mentioned somewhere else (Workshop thread, I think), when we got the Satellite running we found that our rebuilt steering box is/was leaking like a sieve

Rather than try and take it out and give it back to the peeps that did the rebuild, we thought the easiest route would be to try & fix the leak ourselves with the box still fitted to the car.
With many thanks to Anton for the loan of his homemade cover-removal-tool, and the provision of a spare set of seals/o-rings, we now have the cover off and have established that it was, what we presume to have been, an incorrect sized o-ring, positioned in the wrong place!
You can see in the 1st pic the dodgy o-ring and where it sits in relation to the recess that it should sit in.
Looking at these pics that Stu took, it took me a while to get to grips with which surface is higher or lower, and hence whether the o-ring should sit inboard or outboard of the step, but when I saw the last pic that shows one of Anton's o-rings sitting snug against the inside of that step it all became clearer.
So.... before we bolt it back together, refill the oil and start her up to see if the pump still works and if the leak is cured....
Has anyone else had a go at replacing these o-rings / seals and if so, does the last pic look like it's in the correct position?
Grateful for any input

Damaged o-ring in-situ:

Damaged o-ring removed (the smaller one in the middle is from just under the nut above the cover, which wasnt leaking):

New o-ring in different position:
