I've been looking for this seal. I'm just sure that there is a seal out there for the steering box/sector. I've found these two Omix-Ada 18029.03 and 18029.04 but I can't find anyone that lists the I.D. or O.D. of either one. The .04 looks like the one I took out but that doesn't mean anything. I'm sorry if I already asked about these but I just thought someone might know about these, or even better, a seal that fits.
