    Since I do alot of mud/water, I want to put a filler bung and drain bung on my 14ff diff cover. I was thinking a very small fine thread nut and bolt on the bottom for the drain, and a larger (maybe 3/4" or bigger) fine thread nut (and bolt for the plug) welded to the upper half of the stock OEM cover.
    Any other suggestions?

    I don't think I need and armoured diff cover as I'm not in a rock environment.

    Better off to get a piece of bar stock and then drill and tap a pipe thread in it then weld that piece to the diff cover and use a pipe plug.

    X2, use pipe thread (NPT).

    Or you can do like a buddy of mine always does and just drill a hole in the bottom of the housing and tap it.

    yeah but if you want the maximum strength and have your housing shaved, I wouldn't recommend that idea at all.

    KidJethro was making covers for a while with fill and drain plugs. Doesn't make them anymore though. I would have liked to pick one up before he stopped, oh well.
