For sale is a pair of new in the box, never used Napa 66521 front wheel seal. The dimensions are embossed on the seal, 48X62X7, and they are correct for the applications. This seal listing is really unique because because it can be used as a transfer case front input seal, a transfer case output shaft seal, front wheel seals. and rear axle seals. It crosses over to a 1188 National seal, a 224820 National number, an old Napa number 66540, new Napa number 18962.  I changed a customer over from Napa seals to the National brand I sold, and a sticker with the National number was attached. This seal fits 26 vehicles according to the above fitment listing, but it fits many more vehicles, it looks like mostly Toyotas but I have another listing showing it fits Austin, BMW, Chevrolet, Geo, Lexus, Lotus, Mazda, MG, Pontiac, Porsche, Suzuki, and a shipload of Toyotas. I will figure out what is up with the discrepancy . I cleaned the box, took the seal out and cleaned it, and there was no number stamped on the seal, just the dimensions,  to verify accuracy so I scratched off the sticker with the National number on it and found the original Napa number on the box and went with that. The box are a little rough where I scraped the sticker off, but the part inside is in great shape. The key is to get a bargain on a brand name part, no matter what the box looks like. If you have any questions about the compatibility of the parts I. sell and your vehicle, please feel free to contact me through eBay. Thanks for looking, Scotty.
