Yes, it is an 18.5k eaton rear end. I can get a rear end from a local truck salvage yard, with taller gears and cam brakes for (rough estimate) 600-800 with exchange of my current rear end. I wouldn't mind getting the truck to move a little faster, it has 5.73 rear axle ratio and its top speed is 54mph with the wind at my back and going down a steep hill.
