Milano PS pump parts

[christian147@domain.elided]

I saw this question last year but can't find the answer.  Where can get
overhaul parts for a Milano power steering pump?  I think both Audi and
BMW used this pump but which models?

Both of our Milano's pumps leak.

87 Milano (it runs but failed emissions this morning)
87 Milano (it just started running tonight)
67 Gt Jr (it doesn't run yet)
72 Gt Jr (it's crunched)
