Need coils for this balance and mounts

Hello! The coil housing you're showing in this photo appears to be a match for our 15-087. This is compatible with our Series 180 coil spring; I think that stamp in your photo might read "3," though it's admittedly a little hard to tell. If so, that would be our S180-03.

You also mentioned a mount. The Series 180 is compatible with a few different styles, though, and you don't show yours, so I'm not certain what to recommend. The most common is the 16-024 but make sure to compare it with your original before you buy anything.
