Try looking into auto carage shops, or truck shops like 4-wheel supply stores or rigging supply stores. I have had a few made back when I was into 4 wheeling. Essentialy it starts as a straight length of rod with the ends threaded, The threads are important too. Try your best to find ones with Rolled threads ,, not cut threads.. Rolled are much stronger. Once a length has been established from your old U-bolt they put it in a press and presto a "U"... Semi trucks and trailers break those often enough that alot of the repair shops keep a supply on hand.. they may even be able to direct you to someone who has the correct stuff if they don't have it. And keep in mind, They aren't that expencive, so do both u-bolts at the same time.. it's good peace of mind...
