I am installing a MSD box and coil in my bird. Do I need to replace the distributor cap and rotor? I have stock 57 dizzy with petronix electronic parts inside. Taylor wires. Some of you have said the wires are ok but I forgot to ask about the cap. I am still told I need the Moroso wires instead of the Taylors. Just need another opinion .Thanks
