I am using a 2001 Mustang Cobra donor for my Factory Five Mk IV build. I had the key, cylinder and halo ring taped behind the firewall (as per Factory Five) and it work fine until my build mate cut the ignition halo ring on the PATS. Can I get a junk yard (or new Ford) replacement? I assume the PCM and key are the parts that need to match the original car. My concern is that there is a circuit board integrated into the halo ring. Does anyone have experience with this?
