Ford Repair: rack and pinion, mustang gt, interior work

Question
I have a '95 mustang gt conv. 5 sp.  Its in the need of a rack and pinion.  After checking at parts store there is a listing of 4 possible.  How do I tell which one I need?  
ANY and ALL info you can give me would be appreciated.
Car is straight just needs interior work and drivers floor fixed.
Thanks
Rick

Answer
Rick-

  After seeing your year correction, I'd say your best bet is to simply ask the staff at the parts store.  P/S racks are tricky to get right.  In any given year there's usually two different ratios and there's going to be a difference between (in your case) the 4 cylinder and the V8 rack.  As long as you get one for a 5.0L, you should be ok.  The GT does have a specific rack (it's more of a "sport" feel than the LX), but it's more about steering box ratio than actual fitment.  Hope this helps.
