It's been a long time.....
How do you go about checking what gears you have in your 12 bolt rear end?
I remember it being something about how many revolutions the drive shaft makes vs the rear wheels?
Can anyone refresh my memory?

It's pretty simple if you have a posi. If you have a Posi, just count the number of times the driveshaft turns for every time the wheel turns. For an open rear, count the number of times the drive shaft turns for every 2 revolutions of the wheel.

Thanks! I knew it was something like that.
