I have put the window back in. However the 170 series seems to have a longer tapered cut than the 171 series. However the refer to the 170 as being the short series and the 171 the long series. If I knew the distance from hole center to where the taper ends I would know.

The S170-407 Coil Balance appears to be a possible replacement for your original coil.
