Displays for woman e man.ech

Hello, i was wondering if anyone can help me with doubt ...

I have two woman and man with sets of yellow and red and blue Mithril osmio !!

the diplays of them are 12-14 but these ID's are already used by orichalcum sets, and chaos. someone could explain me if you have how to change these displays to other id that are not used?

waiting for answers

Rename the dds filename and mesh to change the display code.

Hint:
Coat_s0 = Display code "0"
Coat_t0 = Display code "16"

then changing the letter s to t as in your example.
because I do not understand very well sorry if you can explain more clearly ?
