schubie

HI, I have a 1998 Outback that I'd like to replace the drivers seat cushion. The fabric is still in good condition but the pad is worn/broken down. I called the dealer and was give part number 64220AC500 and told it was discontinued. by the way the cost of the discontinued cushion was over $300. There is another part number of 64220AC520 for $96 that they told me would not fit my VIN. Does anyone know the difference between the 2 part numbers and has anyone tried it? I saw other posts of people buying the pad from the junk yard or swapping the passenger seat pad but all the ones I can find are in just as bad of shape. Any insight is appreciated. Thanks!
