What rear-end do I have?

[Erkenz]

Dumb question, but I have a differential from a jdm jza70 automatic 1jzgte, and I'm wondering what the gear ratio is? 3.9? or 4.1...?

Thanks, but I guess I'm wondering if all JZA70 Supras came with the 4.11. Or if it was different between the manual/auto's or the TT-R versions of the car.

You could always pull the rear cover and count the teeth on the gears right?
