Is there any type of salvage yard in the Iowa area that works with those. Going to maybe convert a 6 bale bumper hitch trailer to a gooseneck style. Had the local welder price the iron for the conversion for it, just as well buy a new trailer. He said iron has went up in price in the last few months, help him make round bale feeders and the cost of the little bit of iron in those has jumped. Thanks.
