Well going 35 spline doesnt have much to do with it. They are talking not just about the locking hub, but the whole bearing assembly. I swapped hubs on my DRW 60 from a SRW but they are pretty hard to find for cheap. Doug and Extreme Axle sells them new with bearings and brakes for a decent price. Then when you get time, machine them down and sell the DRW to someone else like I did. Easy enough and tons of threads on pirate 4x4.
