No problem, on that trailer, it is a spare 10 inch drum you need, Daigle has them, common size. A bit of a bear to haul around though. Keep in mind the Drums are good for 5 years. At that point you do not want to be trying to take it off at the side of the road. I flushed religiously. With drums, you have to adjust them manually at least once a year, and always make sure you releive the master cylinder when uncoupling. Otherwise at year 6, you will have a hell of a time getting the drums off or the wheels to rotate. The seal is green, 1 1/16 and 1 3/8 this. The offer is there if you change you mind.
