The yellow 261 was installed in the 47 3800 dually. Of course the Rock Auto transmission mounts were too wide and the engine doesn't seat right into the frame. They will be changed out. followed right behind the engine with the SM420, carrier bearing and driveshaft. Need a good source for the dual outlet water pump.....
