Good to know, I went ahead and ordered a pair from RockAuto as well. Good price too, paid $89 delivered. I figure if nothing else it's time they get changed out on my 21yr old car!
Let us know how the shimming goes. I have the same issue as you, the steering shaft is like 1mm away from the header pipe. Everytime I turn right I can hear the engine touching the shaft.
