The dimensions were taken from other hitch plans, so the bottom location is to those prints. The upper 3 point hitch rod is actually for a tiller, I don't know if the upper hitch rod for a Brinly is different or not.
The float on the tractor may or may not be sufficient enough to keep things from bending. Making the slotted link would be easy enough, or even a chain could be use.
Having a vertical or plum link will yield a slight advantage in the amount of "lift". If I were to design another one, I would either bring in the hole in the tab for the link or I might just make a longer upper rod which should yield even more lift.
