Hey guys and gals so I have a bent rear axle so I threw the rear of the car on jacks on stands and i began to spin the wheel to check what side is bent and i realized i have posi now idk what ratio i have i boutght the car with it and wasnt aware it is posi so i need to know how to figure out what gear ratio i have. Rly appreciate any input thank you

Posi doesn't determine the ratio. Read the tag on the diff cover if it's still there. Otherwise just count how many times the pinion turns each time you turn the tires one full rotation.

All GT/Cobras have a 8.8 trak-lok. OEM ratios will be 2:73, 3:08, 3:27. Some exceptions to this. Aftermarket can be a lot of different ratios.

there's slippage in the axel on the open diff. and that will throw off the ratio when counting the DS rotations
