I have a '01 B-series motor swap in my '96 civic. My P/S pump needs to be replaced. Do I buy a B-series or D-series pump?

Furthermore, if the pump is going bad and I do not change it right away can it damage any other part of the steering system?

 

buy a d-series becuase the p/s line bolt pattern does not line up the same as a b-series p/s pump
