Here is a picture showing the XR inner rod (top) and Scorpio inner rod (bottom).

More than once has someone went to put a reman'ed rack in their XR to find out the tie rods are too long because they've been given a "Scorpio" rack. And the parts slingers on ebay (and elsewhere)
all seem to list the same tie rod for both cars. You do not want XR inner tie rods on your Scorpio, its pretty dangerous!
Might be worth a move to the FAQ?
