According to the 1929-54 Chevrolet Master Parts and Accessories Catalog, your 1946 AK shares the same main axle "beam" part number: GM# 3686572. Beyond the axle itself, you need to consider if you are switching over your existing spindles/brakes/steering components between the axles. If not you need to look at the differences in brakes as they changed from Huck style to Bendix in 1951. Brake changes could complicate your swap unless you take them into consideration.
