As others have mentioned before about HF trailers, finding square wall tubing in that odd Chinese dimension is just about impossible. I couldn't find any either sooooooo....I'm having my local steel worker weld two pieces of light gauge angle iron together to fit the oddball dimension of the tongue. He will add 24 inches to the length plus another 6 inches or so inside to strengthen the added length. I'll take a pic when he tells me it's done.
