My friend and I did the 5 lug conv. on my mustang last week, I got my conversion kit from 5.0 Resto. I put 73mm rotors with hawk brake pads in front and for the back i just put regular brakes with the drums for the moment. I also got a new master cyilinder, but i would like to change my brake booster. I am looking into the 93 Cobra Brake Booster but where can i get this booster. Any help is appreciated.
