[94_Lifted_Z71]

I bought a 93 Chevy ECSB and someone has swapped out the rearend from the 10 bolt to a 14, where is the marking on the rear end to find out what gear ratio is in it. The only reason I know they changed them is because I ran the vin and it was supposed to have a 10 bolt. I am pretty sure it has a locker or posi in the 14 bolt because both tires hook up if it spins.
