My humble and hopefully prediction, is the car side of the equation. I bet as soon as you disconnect the linkage push it fully in park the noise will disappear. I hope so anyway.

like we both said! Do not forget to check all the linkage bushings as well.

I have never heard a 727 make a simple ticking noise in park but can only imagine what may cause it.
