71 plymouth satellite power steering

hi!

i have a problem with my 71 plymouth satellite sebring. its power steering transmission is leaking fluid and it looks like a major job. prolly the internal shaft has been damaged as well and i wanted to order the entire unit (rather than the individual parts) through a dealer here in germany. no luck - out of stock. can anyone help me with this issue. i need to get my baby back onto the street asap since i am especting a female visitor in a few weeks! ;-)

btw .... if someone wants to check:
