help with an interpretation of The Bug

[Failed_Hero]

Hey guys, I am working on a simple skope project of placing the scarab jaws from Tommy Boy's Blue Beetle (Jamie Reyes) onto valandar's wwBumbleBeecar mesh.  I removed the Skin instance and added the bits to the desired location but in the character viewer they remain stationary while the rest of mesh work.  How can I fix this so I can create an my interpretation of Ted Kord's Bug
