Which brake proportional valve do I use on a 98 EX?

I bought a 92LS proportional valve and noticed that the lines do not line up to the original civic lines. People are telling me that I need to buy a proportional valve from an integra w/ 4wheel disc and no ABS. My coworker said that i need to use 94+ integra RS proportional valve. Do any one know which valve is the correct one to use on my 1998 Civic Ex, no ABS. Thanks
