They aren't hard to make if you have access to the materials and equipment. If you have broken one, you will break another. I can't remember if the YJ is the same, but the CJ has a hole in the factory hanger that clears a rivet in the frame. That hole makes the factory hanger weak. A new set of factory hangers can be gusseted to add strength, if you don't want to buy heavy duty ones($). I've got a set of Tomken hangers on my CJ that came off of a parts Jeep that I had and they are quality pieces. I think they run about $50 a pair, which is cheaper than I would charge you to stop what I was doing and fab you a set if you came into my shop wanting to have some made.
Wait a second.......you said it would need to be torched off the frame........are you talking about the shackle mount that is bolted to the frame or the spring hanger that the fixed end of the spring attaches to?
