Well, those are all interesting. The first one is for a Mazda GLC and similar, it has a chance of fitting the Ford Courier booster since that was a Mazda product as well, maybe the booster that naturally fits these is 7" or less as well, haven't looked. The second one is for a Nissan Sentra. None of these are for particularly large cars, but they did use disc brakes (at least on the front), from what I understand disc brakes require more cylinder volume than drum brakes, but really it's dependent on the stroke and probably not possible to know unless one gets one. They could also have issues with balance front/rear, again hard to tell unless one got one.
The position of the bolt on the pedal arm doesn't necessarily have anything to do with the pedal ratio. It's the ratio of the distance from the pedal to the pivot axis, to the distance from the master cylinder axis to the pivot axis, measured perpedicular to the master cylinder axis, like in the attached diagram. Maybe they can measure it according to the attached or similar diagram.
