good luck finding a 3/4 ton 4x4 dually. every K series dually i have seen has a DRW Dana 60 under the front, which was exclusive to the 1 ton K30. as far as changing a K30 from SRW to DRW, the front axle is a matter of changing the bearing hubs. everything else is the same. the rear axle is a totally different story. you must change the entire assembly from the current Corprate 14 bolt, to a Dana 70 from a dually. also make sure to get a Dana 70 with a gearset that matches your front gears, otherwise you'll have to regear one or the other.
