Fog lamps should be positioned symmetrically; the same height from the road and the same distance from the sides of the vehicle. The lamps should be fitted so that their outer edges are no more than 400mm from the outer edge of the car. Maximum height above ground 1200mm. Fog lamps should never be used unless visibility is seriously reduced

You have the dimensions but also note that you have one long range spot (the clear) and a fog. They must now be used in pairs with the headlights off and the spot is on the near side to point along the kerb and the fanned fog on the offside tilted downwards. Is this a 3 Litre? The engine bay loom contains the a cable
In a sense, having one of each complicates things slightly as they're designed to do different jobs under different conditions; the patterned fog light lens is designed to reduce light scatter, ie light reflection on the water droplets in fog, at which it generally performs better than the standard headlight light pattern. Historically, a single light used to be fitted on the nearside (as per early Rover 90s), intended to illuminate the kerb/edge of road in conditions of poor visibilty (now defined as less than 100 metres visibilty).
Long range/spot lamps (clear lens) were designed to produce a pencil beam of light with a greater reach than std headlights but obviously would be more likely to produce light scatter in fog. Additional spot lamps should either be dippable (yours aren't, assuming they're Lucas Square 8) or turn off when reverting to dipped headlights.
The measurements have already been covered and there's more detail in the Road Vehicle Lighting Regns 1989, Schedule 5 (regs 18 & 20) and Schedule 6 (reg 20) (unfortunately, can't attach a link) regarding numbers / use etc..
Slightly off-topic but related, just; this thread has reminded me how many new cars no longer have fog lights, they aren't even listed as options, probably because there's no easy way of fitting them. Thinking about mine, one has a set of Square 8 fogs but of the 'moderns', one has fog lights built-in as standard (low mounted but, interestingly, clear lenses), one has 'intelligent' lights and another has led headlights, neither of which have any fog light fittings. I haven't driven either of the last two in fog so can't comment on the manufacturer's view that fog lights are no longer necessary with the new set-ups.
However, many new cars now have cornering lights, so perhaps they've taken up the space previously used by fog lights; cornering lights seem to be becoming a better indication of which way a car intends to turn at junctions etc, as few people seem to indicate these days

There are far too many lights on modern cars which are unnecessary on well lit roads and create glare on wet roads. I recently upgraded our 3 Litre lights to LED to reduce load on the dynamo charged system. The are very good. We use this P5 a lot at night in the dark and also had a quite a few headlamp flashers as our 45w dipped beams looked like I was driving on sidelights to oncoming cars! Have put LEDS in the sidelights too!
