Derek,

  Yes, there is a part # difference.  Not sure of what the difference is
in the two boots?

  251 498 203 F is the one I stock and sell.  I've installed this part #
on 87 and 91 Syncros without a problem?

  Now these boots are the white boot.  i wonder if the oe boot prior to
the 89 was a Black Boot??

  Either way, you're right about the *Fiche* and that mid 89 there is a
part# change on the film.  If you have the part# I gave I don't think
you'll have a problem though?

  Hope this helps?

  Kyle
