The Olathe Toyota online search engines list 90311-34023 for the right side seal which worked for my 1999 Corolla A245E. The same site list 90311-34026 for the left side seal which I have not actually checked.
Did you get the part from a dealer or...???. A lot of aftermarket parts on E-bay are counterfeits listed under wrong part numbers. Even if the sticker on the bag says Toyota, not a guarantee because they fake those too.
