Divide the two numbers and this will give you the gear ratio! to tell if you have a posi or not when you have the cover off, if you see springs and plates in it then its a posi, but if you only see gears and it looks all open, then you have a non-posi! this is what a posi looks like! http://www.gtoforum.com/attachments/...ctory-posi.jpg
Ummm yeah,
I pulled my rear diff cover off and looked, but I did not see any numbers.
But then, I cannot say I know what ring gears are either
All I know for sure at this point is that I have a posi rear end.

Now I need to get new gear oil, and figure out how to refill it.
