Yup. I sell it too. Part number 253 069 183A, $19.95;  including the p-trap,
hose, drain cap, and floor fitting.  I list this as fitting approx. '86-91,
as the earlier Westies were a bit different. It's been a while since I had
an early 80's model so I can't recall the exact difference.  I would think
that you could easily fit this to an earlier one, too, though, since the
sink is the same, although I cannot say that I've tried it myself.

        earlier models are different. I was at the Busdepot physically last
year and looked at the actual parts. And yes one could replace the "whole"
setup, but as somebody else mentioned it might be quite a butchering job (I
tried to unscrew the upper part, but it's either glued in or something else
makes it stuck) and then the upper drain might not be flush with the bottom
of the sink.
