Book says to fill to the level of the upper plug, so that's what I do.  The extra pressure on the seal is very minimal, it should be able to handle it with ease.

Don't forget, all the steering components on a TR3 originally came from some other car (mostly a Mayflower as I recall).  Likely the fill plug on the box was used in a different application.
