7890, how can you tell the difference between a 3.55 & 3.94 differential

I've looked at them, according to the 3.55 writeup, it states that the 3.55 is the smaller of the two.
from the 3.55 writeup, "5. Place the bellhousing clutch side down on your workbench, place the 3.55 differential in the housing. If you confused the two differentials because you are not organized, the 3.55 is the smaller of the two ring gears."
Well, i can't tell. I'm not a dumbass damnit. It looks like the 3.94 has ID Marks that correspond between the differential splines and the output shaft splines.
There are also raised, stamped numbers & letters on the differentials that may distiguish them so you can get the correct one if you need to. There has to be a damn difference...
