I will be following this closely as I am in the exact same situation. I am also considering a spiderhill swaying zombie kit or the leering kit if it gets released. please share any tips or close up photos if you take any. Would be much appreciated.
Thank you so much!There is another current thread from a member that bought a talking skull from fright props and mounted it on a Costco skeleton. In his post he has a video where he shows how he attached it. Check out that thread. I think he used a threaded rod and zip tied it to the skeleton.
