Did yours break? Is the bracing all cracked? If this is why you're looking for one then I can tell you it is repairable. I fixed one for a friend of mine with a 90 p/u some years ago and it still works today. It would be better to reinforce it and repair it if you can so you won't have the worry or expense of it breaking anymore. Granted there is some welding involved to make this repair and it must be removed to do this. Just a thought  . Either way, good luck and I hope it works out for you.
