<VV> gear lube leveling problem

Looking at a mated differential and transmission, without measuring, the two 
filler plugs look to be located about halfway between the lower two cases 
mounting bolts.. Of course, if ideally they are exactly equally located, and 
the cast boss is large enough, it might be possible to have a filling plug 
hole drilled slightly off "up" or "down".
