is the spline count the same?
I believe so. Some are C clip and others are not, but the splines are the same. Both have 30 spline axles.
Same size axles, different gear ratios within the axle housing. 4-cyls are generally 4.10 6-cyls - Manual transmissions are either 3.07 or 3.27 depending on the yearAuto transmissions are generally 3.73
Yes, the spline count is the same on both.
