sportpilot steering adaptor collar

[klauricella]

I had to remove my autopilot to replace steering. In the process the adapter that goes from the helms 3/4" tapered shaft to the autopilot 1" taper was destroyed. Everything was seized together. I am having a hard time finding one I have emailed the manufacturer but figured someone would sell them to put a wheel with one inch hub on a standard helm.
Thanks
