Does a stock 1977 dodge power wagon have all time four wheel drive or is it suppossed to have hub locks on the wheels?

A stock half-ton 1977 Dodge Power Wagon should have an NP203 transfer case and a Spicer model 44 front axle. The NP203 is a full-time transfer case with a locking differential in it to allow for a selection between "four-wheel drive" and "all-wheel drive". In other words it would send equal power to the front and rear axles, or divide power between the two axles based on driving conditions. The Spicer 44 front axle is not suppose to have manual locking hubs on it due to the fact that the NP203 transfer case is always sending power to the front axle.
