How would I detect Body Types

So in my game, when players join, a motor6d attachment occurs where the “sheath” object shows up on the humanoidrootpart of the player, however, never took into account how I’d make it look “normal” for other r15 body types

Example

How it’s set up right now with normal r15 Blocky Bodies

Any solution to make it fit properly position wise with different r15 body torsos?
