The rotors mount on the front hubs, which are likely stock. Accordingly, the grease seals will be the stock sizes. The only aftermarket hubs I’m aware of are made by IPSCO but they probably use stock sized bearings and seals too.
Dennis Quella makes (or once made) aluminum front hubs. I made my own from 7075 on a 6" lathe, to mostly stock dimensions. I think everyone uses the stock sizes.
