There's practically no chance of finding a mk4 PAS rack. The best fits are Escort mk5 and Nissan Bluebird. I have both of these rack and trial fitted them to my spare bulkhead. None are plug-and-play though. If I had to do it again, I might go the mk5 route. This will require removing the rack mounting panel, but after that it will be quite straight forward. The bluebird rack will mount to the original mounting location, but needs modifications to rotate it around it's axes. The steering column input shaft will point quite straight up otherwise. I still have the racks, if you need some measurements or something.
