Custom Car texture is broken when used on Addon

Hello didnt know where to post this question. So we made skin textures for our departments. If we add the texture to a normal replacement the texture loads fine. But we are trying to add more police vehicle options to the server. So making our cars addons and the texture wont load. Either the car is pink and yellow or a green and ashy color. Anyone know a easy fix?
