The correct Bearing Buddy for your trailer depends on the inner bore of your hubs. Thank you for the axle reference information but this tell us other things (axle length of 89-inches and spring seat spacing of 74-inches) but not which hubs you have on your spindles.
The linked page displays all Bearing Buddy grease caps which are made in sizes to fit hub bores from as small as 1.781-inches, part # BB1781SS, up to 2.717-inches, part # BB2717SS.
The best way to measure your hub bore is with a digital caliper like # PTW80157. Measure to the nearest thousandth (e.g. 1.234-inches) then use the linked page to select your size. Please refer to the linked photo for help in where to measure.
You may be interested in a grease gun # PTW54290 for filling the Bearing Buddies with grease and the linked article on grease formulations may be helpful.
