Need a bit of guidance on how to do custom armor.

Hi!

i have been trying to put a set of custom armor into ark but i am having little luck at doing so, i know its a skeletal mesh but i cant seem to find the right bone to attach it to.
is there a tutorial somewhere, i have been searching google and youtube for ages now but cant seem to find any. even a small bit of help would be greatly welcome.

thanks to any one who will help and credit to that person will go into my mod when its done

Edit : i have it connected to the ROOT_INT_SKL at the moment it seems to move with the pawn but not as the pawn does in that it doesnt move up and down when i walk with the pawn like the other armor in the game does.
