need help on mc swap
 

I finished up the t-coupe brake upgrade on the rear of my car, have the new proportioning valve all ready to go, and now I am looking at putting in a new 2-port mc, the one I have is a lincoln. what is the best way to do a 3-2 port conversion? I have seen kits sold by people, but nothing for my mc, am wondering if I just shouldn't take it back and order a 94/98 mustang one?
