Springs are not that hard to make. You have the old one so you know the approx length and thickness. Just get some banding material or another old spring of the approx thickness. Heat it up with your propane torch. Let it cool on a brick. Shape and drill the appropriate holes. Bend to the approx shape. Reanneal as above. Once cold, heat it up to where it is not attracted to a magnet. That is about 1475F. Quench in oil - peanut, canola, something. Shine it up with fine sand paper. Heat it up to where you can see the colors - shoot for a dark blue. Try it. If it needs to re-bent, Reanneal, Bend, Harden and try for the blue again. If it breaks, go back to the third sentence. Maybe go to a bit lighter blue, but it shouldn't break. Try it, what have you got to lose? This is therapy!
