I need help on a mod

[User4352]

Hello, I need help on a mission pack mod that I downloaded for my GTA Vice City I explain better, I use the police mission mod pack uploaded to you tube and when starting the missions for SWAT, I saw that my character changed to the French SWAT from GIGN [Fsfa, code inside the img]. I wanted to use the normal Vice City SWAT skin instead of that, I went to the game database .img file using the IMG-tool and replaced the Fsfa skin with the one Another SWAT that I wanted. I started the game and when I started the first SWAT mission, the skin that I had replaced appeared, they were satisfactory results. But ... After that first mission is over, I went to the checkpoint to start another, the police missions, and to start that mission it is necessary to take the equipment, and the uniform, when I go to where the figure that marks the location of the uniform is. police, the character that appears on the screen is the Fsfa that I replaced, and that no longer exists in the database of the .IMG file and has left me several doubts, how is that possible? I would like you to ask me that question mainly. And I would also appreciate if you could help me to know how I can make the one I want appear instead of that skin, and in what way and with what program I can edit and replace the skin that appears when I take the police uniform, I want to use SWAT skin from Vice City. I would be very grateful if you could give me some valuable information or help.
