Backpack Equipping/Unequipping 3d accessories

Hiya! so i have custom 3d mesh hairs that have been fully weldconstrained and all that jaz, My next problem is making it so that these hairs can show up in a super simple backpack gui. We have an already working backpack the only problem is figuring out how to get the hairs there.

Right now the backpack only shows whats in starterpack as a ‘‘tool’’ but im working with accessories here. How does one do that? pictures will be included.

these are the hairs im working with

this is how the hairs are welded onto the bodies.

here is the backpack gui we are working with just for tests. Please let me know if there is anything else you need to know - script side, whatever it may be.
