Can't put it off any longer.  The pump I got (Graf) includes the big O-ring
and the two gaskets on the pump, but not the small O-ring for the pipe that
slips into the T-stat housing. I need that, and I think that pipe has to be
detached from the engine at the other end to get at the pump, so I'll need
that gasket too.  It's been 20 years since I've done this job, and the
Bentley doesn't have any instructions, just a diagram.

Are these dealer only items, or have any of you found a source?  Are there
any other gaskets I need?

I'm going to find out how much it will cost to have this done tomorrow just
to see if it's worth doing myself.

Thanks!

Stuart
