- 1973 Fastback Mustang Mach 1 351Q 4v
Hey everyone so I recently bought a 1973 Mustang Mach 1 Fastback 351 Cleveland Q code (If this info helps). I wanted to know what this is for if anyone knew. Let me know thanks! Just in case it isn't clear its on the left side of the engine bay in the far back near the firewall.
