I know this sounds like a complete newbie question but here it is. Does anyone know what size socket wrench fits both the drain and filler plugs on a 1994 z71 NP241 transfer case"they are the same size"? I know this seems like a dumb question but the filler and drain plugs are a large odd size. Later models have smaller plugs. I have a good craftsman set but none of my sockets are that large. Its possibly a 30mm or so larger than a one inch. I really can't afford to buy a complete set and want to buy a single piece. Any help is much appreciated.
