Cheers,
Bought a new 22' last year on new EZ Loader trailer and I did not order the swing tongue. However, I was discussing it and the dealer told me that it could be put on afterwards. So I would believe that you should be able to pick one up. I purchased my motor/trailer from Parker Marine in Nanaimo but am quite comfortable suggesting that any EZ Loader rep should be able to obtain parts for you. They are warehoused in Vancouver.
