Are you aware that the Canadian Ferrets had different hubs than the Brit hubs? The Canadians apparently improved the hub internals. If you won a surplus Canadian Ferret, it will have the different hubs. Towed one for about 300 miles once at about 50 MPH behind a Deuce and a Half, but those are not towing eyes, they are for tie downs. I hated those vehicles when I served. Still do.
