I'm changing the fluid in the rear diff (locked 05) and I don't know what size hex key to us. Does anyone know the size. I don't have one large enough and would prefer not having to buy a full set. I did try a 1/2" and it was too large. Not sure if i need to go 1 or 2 sizes down or need metric or ase. Any help would be appreciated.
