Wanted: Parts for a Calcomp 5536 plotter

I have an old Calcomp 5536 that makes very nice plots, but lately It
has been giving me service station errors. I think the pads on the
service station have gotten so hard that the step motor in the service
station can't push the pads against the heads any more.

So, If you have an old Calcomp 5536 sitting around, I would like to buy
the purge unit/ head service station out of it. I am willing to pay
around $100 for the unit.

please email me pictures of what you have if you are interested.
Thanks,
C. Alan
