What would you do?

What would you do if your wastegate arm end was rotted away (circle that connects to swingvalve is now an open "u". I could superglue a washer to it. I could cut and thread to make an adjustable. I could replace the wastegate can assembly. I'd like the easiest fix that will last a long time. Whatcha tink?

You could cut and thread, I've done that, but the best, easiest thing to do would be to replace the wastegate.
