The 95+ trucks do run a larger diameter rotor with the new style calipers, your stock one will probably work, but, for the price of a set of rotors, it's a pretty cheap brake upgrade.
So, the wheel hub, bearings, and lockout from your D50 are a direct swap, the rotors are 95-97 specific, but they are the same thickness, just larger diameter, so you can use your 92 style rotors with them if you choose.
