I know it's been covered before but if u have a nardi wheel, 2 pot brakes and car was built in early 1998 as your was then you have a MY98.
If in any doubt ring a Subaru dealer with the VIN they will soon tell you what MY it is.
As for a wheel I would just look at aftermarket momo.
Too many iffy legal issues with airbag or converted airbag wheels.
