The standard fan on a 69 GTO was a 19" 5 blade flex fan with a 19.5" declutching 7 blade fan optional (standard with AC). The fan shroud was designed in a way that the fan was several inches below the top of the shroud but very close at the bottom. As mentioned any issues with engine mounts, bent frame rails or even trans mounts can cause the fan to hit the shroud near the bottom.
