To go open drive, it takes more than just modification of the rear axle input. The rear axle will need suspension components to allow it to move but stay in the right place. This generally takes a new set of stronger radius rods to include a strong torque arm or a set of semi-elliptic leaf springs to hold the axle in position. This adds a lot of work to this type of modification. Keeping the old buggy type transverse spring saves a lot of further modification if a person can find the right machine shop, drive shaft shop, or kit fabricator to modify parts to work a torque tube.
