Alternative #3: If you insist to use 7mm original collete from Novarossi, You can buy Mugen Seiki H0756 ( the last part that hold the thrust bearing ). H0756 is longer than Xray.
BTW, check / read again the Xray manual about clutch gap vs end play before going to alternatives.
#3 seemed to be the best option for me because I already have a few kyosho clutches around. Even after filing down the collet to 5mm (from 7mm, and this was hard to keep a square collet) I ended up needing too many shims to get the clutch bell off of the clutch shoe to be able to set the end play at all so the piece that holds the thrust bearing is still better.
