Soldering is very difficult. I got it once, by heating the small amount of solder that was already there. But it came off as I tried to adjust it. Here's my recommendation: set the z-spring down in place and hold it there with tweezers and place super glue in the tiny hole. I think that should keep the contact, and since the glue is being applied from through the hole, it won't prevent the piece from conducting the electrical signal. Wish I'd done that. Now my z-spring is unusable. Does anyone know where to find one?
