Change Playermodel for admins and higher but restrict players from changing theres.

Title

I am wanting to use this in dark rp

so i and my admins can change our playermodels but normal players cant

i am aware the assmod plugin allows all players to change their Model and if someone could tell me how to modify it for my needs then thanks.

what’s the point in changing in DarkRP?

Classes are made with certain playermodels as to fit what the class is…
