Rear discs are available to work with both taper and Green bearings though not all kits will work with taper. The link shows a Dr Diff kit installed with taper bearings. The axles usually need lengthened a little bit to account for the thicker caliper mount plate. I lengthened by welding a thick hardened washer on the end of each axle and then removing material to get the length right so they contact the thrust button and allow adjustment of end play.
