I just bought one for $130 on Ebay, then couldn't use the darn thing :angry5:. I was going to install it in the front of my '98 Cummins, but I recently swapped in '01 axles and the shafts are now 1.5", 32 spline. I didn't figure that out until a few days before the gear swap I was doing. I also put a Power-Lok in the rear. I thought about ordering the 32 spline side gears for my diff., but that was another $225 or so and that was NOT going to happen. You might check to make sure it is still 30 spline.
