What are the phyisical ways of telling an 8.5 rear from a 7.5?

Look at the pumpkin.........one will have lil ears on the botton and the other will not.........that's comparing the 8.5 to the 7.5 that is

I've always been able to tell the difference by noting that the 8.5 has a much rounder cover when looking at the cover from the rear of the car.

x2..the 8.5 is almost perfectly circular, while the 7.5 is more squarish, with rounded corners, if that makes sense.
