I don't think they're really rare, came on a buncha cougars.
I don't think Roush is Eibach. I know other companies have done that. Like Toyota's TRD springs are just Eibachs.
They might not have been rare when you bought them, but who's going to have them now?
About lowering the car on stock struts:
Don't do it without planning on replace them within a few months. I was stubborn and didn't listen, so I was changing mine after about 3-4 months.
