I was checking info about a Dana in Hollander the other day and noticed that 1n 1970 Chrysler offered 2 Dana's for the 70 B Body cars only , 1 was a 23 spline offset axle one offered for the 68 to 70 B bodies and 2 was a 35 spline equal axle type for the 70 B body only. Is this true and why was #2 built that way? I was more familiar with the offset axle one and thought that was the only way they were built.
