WTB: VV-IX Worm/Endless Screw/Spindle..pick your terminology

[Tinkerbell]

I have a warped spindle on a VV-IX motor, which I believe is the root cause to the undisclosed source of some noise while the motor runs. I have tried one spindle replacement, but it turned out to be just a wee tad too large in diameter and the threads were also a bit longer than my own. Apparently, it was a pretty exacting fit for each model motor... not much tolerance forgiveness.

Here is a photo of what I have and am looking to replace. If anyone has an unwarped one that they are looking to sell, please contact me.

Thank you!
