So I am not sure how to do this, I thought of putting parts inside a billboardGui but I am not sure that would work, could anyone tell me how to do it?
I found out by myself, here is how in case anyone is wondering:
Create a part
Create 6 surfacegui, and a frame inside each of the surfaceguis.
make the adornee of each surfacegui the part you want to have X-RAY
Put the surfaceguis on each face (top, bottom, left, right, front, back)
Make the frame's size {1,0},{1,0} and color it whatever u want.
Enjoy!
