Mobilfluid 424

Getting ready for 200 mile service on my 2016 Kodiak (wet brake in rear differential). The owner’s manual calls for the Mobilfluid 424 for the "final drive". It needs about a half quart to refill. The smallest container I’ve found to date is 2.5 gallons for $78 at Grainger. Does anyone know of a smaller container and have a source? Is there a specific yamaha substitute that I haven’t found?
