Unity Network Player Classes, different models

Here is my code.I use playerPrefabIndex and change this value with button.

 using UnityEngine;
 using System.Collections;
 using UnityEngine.Networking;
 using UnityEngine.UI;
 using System;
 
 public class MsgTypes
 {
     public const short PlayerPrefab = MsgType.Highest + 1;
 
     public class PlayerPrefabMsg : MessageBase
     {
         public short controllerID;
         public short prefabIndex;
     }
 }
 public class NetworkManager_Custom : NetworkManager
 {
     [SerializeField]
     Vector3 playerSpawnPos;
     short playerPrefabIndex = 0;
 
     // etc.
     public void StartUpHost()
     {
         Debug.Log(playerPrefabIndex + "is host");
 
         SetPort();
         NetworkManager.singleton.StartHost();
 
     }
 
     public void JoinGame()
     {
         Debug.Log(playerPrefabIndex + "is joined");
 
         SetIpAddress();
         SetPort();
         NetworkManager.singleton.StartClient();
     }
 
     private void SetIpAddress()
     {
         string ipAddress = GameObject.Find("InputFieldIPAddress").transform.FindChild("Text").GetComponent<Text>().text;
         NetworkManager.singleton.networkAddress = ipAddress;
     }
 
     void SetPort()
     {
         NetworkManager.singleton.networkPort = 7777;
     }
     public void ChangeVRMode()
     {
         if (playerPrefabIndex == 0)
         {
             playerPrefabIndex = 1;
         }
         else
         {
             playerPrefabIndex = 0;
         }
         Debug.Log(playerPrefabIndex + "new index");
     }
     void OnLevelWasLoaded(int level)
     {
         if (level == 0)
         {

         }
         else

         }
     }
 
     private void SetupMenuSceneButtons()
     {
         //    GameObject.Find("ButtonStartHost").GetComponent<Button>().onClick.RemoveAllListeners();
         //  GameObject.Find("ButtonStartHost").GetComponent<Button>().onClick.AddListener(StartUpHost);
     }
 
     private void SetupOtherSceneButtons()
     {
 
     }
 
     public override void OnStartServer()
     {

         Debug.Log(playerPrefab.name + " spawned!" + msg.prefabIndex);
         base.OnServerAddPlayer(netMsg.conn, msg.controllerID);
     }

     }
 
     // I have put a toggle UI on gameObjects called PC1 and PC2 to select two different character types.
     // on toggle, this function is called, which updates the playerPrefabIndex
     // The index will be the number from the registered spawnable prefabs that 
     // you want for your player
