I guess I was as exhausted when I posted above as I am now - ignore that (and this too, if it doesn't make sense).
The spindle bearing seal is 3 pieces (1 rubber & 2 hard plastic), but it's only shown in this diagram as parts #2 & 3.
I wouldn't be surprised if the aftermarket (old-style) part isn't identical to OE, but it's functionally
Item 2 is Ford F3TZ1S175BBA
Item 3 is FOrd F3TZ1SZ175AA
Item 6 is NAPA NOS25009
Item 7 is Napa NOS23276
Ford has replaced some of the numbers with seals that are not correct. When I did mine last year (96, not sure how closee to yours), the parts guy new his stuff and said when they crossed some numbers they didn't get it right. I went to five dealers and each had the same problem.
Don't go to Pep Boys and get the seals they sell. Even though they are Chicago Rawhide, same as Napa relabel, they are not the better ones. The parts they have are a very cheap version, which may work, but I wouldn't trust.
Napa had to order in the 25009, but they got it in a day.
As far as seal 3, the one I got new from Ford was one piece, but the one that came out broke into the three pieces. If you get the Ford one, you will see how easy it is to snap apart. Seal 2 is actually a smaller version of seal 6, but the oneFord parts guy said that they don't have a replacement. Fortunately Napa has one.
They have one part D3TZ3C132A that they try to sell. It is a metal slinger that could be pressed in place of seal 2, but it has no sealing properties, just a stamped part that looks like a washer with a lip where it slides over the axle.
