Here's a photo of RS2000 track rod ends from EDS. I mounted them about 7 months ago, obviously they didn't see any road use.
(click the image for a closer look)
What you can't see is that the nut is fully done, but there's still wobble in the taper. I didn't notice that until yesterday.
I would say this is conclusive evidence that the Escort RS2000 track rod ends do not fit Sierra hubs. (And EDS joints are past their expiry date).
