Do I have 4.10's if my Axle Code is A10A? I figured that my axle ratio was a 3.9 or something similar and that 4.10's came on Auto SR5's w/ 31" tires?

I wonder if the front diff can still be used for a while with 2 teeth missing?

Are 2nd Gen 4Runner and Pickup 7.5" front diff's the same as the T100's? Does the T100 just have longer CV's to make up for the increased width?
