Hey man...Im not sure if this is what you are willing to go through, but when I installed my SYE i mucked up the seal while installing it. I work at Autozone so I hauled butt down there at night and just started matching them up. I found one or two that were almost exact. Nice fit in the housing, and great seal around the shaft. Ill try to figure out the part number tomorrow while Im at work...but if not, and if you are near an autozone...the guys will either help you find one or let you back at the seals to match it up. But Ill try to get you the number. By the way...I couldnt cross the number off the seal either...dont know why. I looked in the books and in the computer but no luck. The seal I found was a timken... Good luck!
