I was wondering if the fender tag is supposed to say which rear end the car comes with or what gear ratios? I heard all e bodies come with 8 3/4 rear ends. So if this is true maybe that's why my fender tag does not say the rear end? And also is the gear ratio or positraction info stamped on the rear end anywhere? Or does the numbers on the rear end onkt say if it's a housing for certain vehicle certain years. That way I don't have to open it up to know the gears and if it positraction or not

 

I had Two 1970 Barracuda's,and only one had the 8 3/4 rear end.
I believe those are all sure Grip.
If you need to know the ratio,you can do that by removing the drive shaft, raising one wheel,put chalk on the tire,counting both the rotations of the wheel Vs the full rotations of the Yoke.
I have done it before,but don't remember the exact procedure.

 

If it hasn't been molested there will two tags under the bolts on the rear end.. One to tell the gear ratio and another one if it is a sure grip...
