Iwill try the standard gxv120 module on the 160 tmrw,the armeture is the same thickness so I will use the spacers. The armeture on the standard 140 module is a fair bit thinner and so is the replacement 160 module but they still match in with the flywheel magnets and from what I can tell you would use the spacers on either 140/160 flywheel.
