It looks like just the shoe is broken. See our 15-087, this looks like a good match. If you need the other parts, as well, you can look at our Series 180 coil spring, 16-024 mounting bracket, and 15-086 housing. Keep in mind you only need to replace the parts that are damaged, you can re-use the rest.
As for removing the shoe, we have another method you could consider, if you are not sure about the jamb spreaders. |

The easiest way is to read the number currently printed on your coil spring and match it up to our Series 180 options. If there is no number, or if it wore off, you'll need to weigh your sash and divide that among the springs your window uses. Since your window appears to use 4 springs, you would divide your sash weight by 4. For example, if your sash is 24 pounds, you would need four S180-6 springs (6 pounds each). Hopefully that makes sense.
