rear bearing mod????

[rcnrider86]

So i needed to replace my rear bearings. Didnt have much money but for $210 i bought a dg o series, rear bearings and seal kit, dyno jet kit. What size drill and tap do i need for the grease insert that i put in the axle housing when replaceing the rear bearings?
