Like Port Royale In Multiplayer I Need To Know The Number Of Ports On A Rack And Pinion?

I need to know the number of ports on a rack and pinion? - like port royale in multiplayer

I have a 1990 Oldsmobile Delta 88 Royale, and I need a new medium and pinion. How can I determine how many lines in it? In addition, someone has access to an online user manual, or can anyone know a site that is free? Thanks
