Does anyone know what years these two versions of the left differential case were used? Thanks!
The one on the right is earlier.
I don't think I have ever run on to either. I have a 13 which is different as the axle gears are smaller,and I have seen 3-4 changes in the other side of case for better lubrication.
There was also a version that used studs in place of the three through bolts.
