Will I need the dust cover off the larger rotor setup? Looks like it is easier to get the whole stubaxle and dustcover assy instead of trying to remove the dustcover. What I've got already is AE102 front caliper assy, new AE93 vented rotor(258mm x 22mm) and original AE92 stub axle and dust cover assy(originally 243mm x 13.5mm solid rotor). Does the axle hub have to be removed from stubaxle to remove dustcover?
