Default Diiferential fluid

Finally got around to changing the fluid in my 71 gto with the 10 bolt. Car was on stands but tires were about 2" from the concrete. Put in one qt of 80/90 then the 7 oz of posi fluid. Topped of with the second quart until the fluid came out of the fill hole. I had bought a 3rd qt thinking i might need it. Long story short i ended up putting in about 1.5 qts all together. Seems like less than i should have? Could having the tires up make the difference?
