not sure think its orgy giro1 exact same as new school ones
Gyro II has Screw threads
Gyro I has Screw threads with a split in the thread to get the cable through (The ball at the end is too big to fit through the hole). On the Gyro II the balls fit through so no need for the split.
Get a picture taken and let us have a look!!
Come on, dont be shy!!!

PS. You can get spacers for the headset if you need to!! Ask OrgasmDonor!! He was selling a set!!
