A GL-4 gear oil is probably better here, these days. OMD-330 has a specified 100°C viscosity of 16.8 to 22.8 cSt; check your preferred supplier's data-sheets to narrow down your options. You want an oil that meets API GL-4, and has a kinematic viscosity @ 100°C that is somewhere near the specified range.

My preference is Smith & Allen's Geartech 75W-90, which has a viscosity of 14.7 cSt at that temperature. Whichever oil you choose, do bear in mind that the gear bushes and synchro rings are bronze alloys, so it must be safe for yellow metals.

My recommendations for the gearbox stand here, too. As does the warning about yellow-metals, due to main-shaft gear bushes.

Do not use EP oils (e.g. EP140), due to the risk of damage to bronze components such as the winch worm gear.

The only yellow metals in the steering box are some lead-bronze bushes for the pitman-arm shaft. Up to you whether you want to use EP140 or straight SAE 140. My understanding is that it should not cause any harm here.
