I am converting from 4 to 5 lug and also going to rear disc. I got the front and rear disc set up off of a 95 GT and also bought a booster, master cylinder and proportioning valve off of a 94-98 GT (not sure exactly what year). My question is can I use the booster, mc and prop valve on my car with out any modifications or do I need to something else to make this work. I have read a few articles on line but they just talk about what you need to do if your using the same mc or a different prop valve.....Thanks in advance.
