I think you are mistaken. I said your inners weren't compatible between the two QRacks, but your outers are. I believe you said the second rack was from an 06? Moog outer tie rod ES3712 is listed for an 02 and an 06, Impreza and Forester. If your shop replaced the outer tie rods that is their error. Again they should have known that.
All someone has to do is turn the shaft lock to lock on the bench on the first rack to see if it is smooth. If it is all this drama ends and the shop screwed up...twice. I'm sure Ashkay and Tibor suspect this so they are done with you and your shop until they see a rack. That's a reasonable position.
