Aerial 20T Speaker Stands

I just purchased a set of Aerial 20T speakers and unfortunately the seller did not have the spikes and knob assemblies speaker stands, he did have the cross bars. Aerial is in short supply of the hardware and is not selling any separately. I could use the following help.
1. Does anyone have the hardware and willing to sell?
2. Are there any photos, drawings or other information
that someone may have to have a machine shop make?
3. Any ideas other than above?
4. A source for premade stands or source for making

Thanks for all your help
