Help Please with Steering Rack For 350i

[gupper]

I have just taken ownership of a 1985 350i which has been garaged for 4 years. This is a non-power steering model and I have just been advised that the steering rack has seized (although it is Very Heavy the car does still steer).

Can anyone advise on a low cost solution (as funds are pretty tight at the moment) and / or where I can buy a new steering rack from and what make / model is required? Also, has anyone else experienced this problem?

Any help that you can provide will be gratefully received!
