steering rack

[Beany-s12]

any1 know how much a new/recon power steering is for a mk2 and where i can get 1 quick? mine blew today when i moved it after it had been standing for a couple of months! had to take the one off the car i'm breaking but thats a little damp around 1 end! all the motor factors are saying 1-2 weeks!
didn't they make some early silvias without p/steering and if so would a manual rack fit straight on or would the colum or mounts need changing?
