If you can not get the part or do not want wait to get it this may be a job for JB Weld. Bend it straight, get rid of paint, scratch or grind it up, apply JB Weld, let cure/dry a day of so, grind off unwanted JB Weld and paint if this works. You may be able to add additional JBW around the outside edge for more strength if it will not interfere with operation.
