What are the addresses of CVehicle/CObject_Add / Remove?

I am trying to conduct some AI experiments for multiplayer based on client side. For that I enabled automatic vehicle spawn, automatic ped spawn etc... but the pGame->GetPools it not being correctly updated with the vehicle information. I found out that the PED's are being updated correctly thanks to the following code found in CPopulationSA.cpp in sa_multiplayer:

  
DWORD               pedVtable; 
  
VOID HOOK_EndOf_CPopulation__Add(); 
VOID HOOK_CPopulation__RemovePed(); 
  
#define HOOKPOS_EndOf_CPopulation__Add      0x612C76 
#define HOOKPOS_CPopulation__RemovePed      0x610F20 
  
#define VTBL_CPlayerPed                     0x86D168 
  
CPopulationSA::CPopulationSA() 
{ 
    dwPedCount = 0; 
    HookInstall(HOOKPOS_EndOf_CPopulation__Add, (DWORD)HOOK_EndOf_CPopulation__Add, 6); 
    HookInstall(HOOKPOS_CPopulation__RemovePed, (DWORD)HOOK_CPopulation__RemovePed, 6); 
    pSingleton = this; 
    m_pCivilianRemoveHandler = NULL; 
    m_pCivilianAddHandler = NULL; 
} 
  
VOID _declspec(naked) HOOK_EndOf_CPopulation__Add() 
{ 
    _asm 
    { 
        mov     pPedStorage, eax 
        pushad 
    } 
  
    pSingleton->AddPed ( pPedStorage ); 
  
    _asm 
    { 
        popad 
        add     esp, 0x3C 
        retn 
    } 
} 
  
VOID _declspec(naked) HOOK_CPopulation__RemovePed() 
{ 
    /* 
    00610F20  /$ 56             PUSH ESI 
    00610F21  |. 8B7424 08      MOV ESI,DWORD PTR SS:[ESP+8] 
    00610F25  |. 56             PUSH ESI 
    */ 
  
    _asm 
    { 
         
        push    esi 
        mov     esi, [esp+8] 
        push    esi 
        mov     pPedStorage, esi 
        mov     ecx, [esi] 
        mov     pedVtable, ecx 
        pushad 
    } 
  
    if ( pedVtable == VTBL_CPlayerPed ) 
    { 
        _asm 
        { 
            popad 
            pop     esi 
            pop     esi 
            retn 
        } 
    } 
  
    pSingleton->RemovePed(pPedStorage); 
  
    _asm 
    { 
        popad 
        mov     ecx, HOOKPOS_CPopulation__RemovePed 
        add     ecx, 6 
        jmp     ecx 
    } 
} 
  

I however cannot find the same code for CVehicle or CObject, could someone give me the adresses of all the required stuff so I can make the same for CVehicle and CObject? I want it to update the pools just like CPed automatically does thanks to the above code.

  
#define HOOKPOS_EndOf_CPopulation__Add      0x612C76 
#define HOOKPOS_CPopulation__RemovePed      0x610F20 
  
#define VTBL_CPlayerPed                     0x86D168 
  

  
#define HOOKPOS_CVehicle_Create      ???????? 
#define HOOKPOS_CVehicle_Remove      ???????? 
  
#define VTBL_CVehicle                     ???????? 
  

  
#define HOOKPOS_CObject_Create      ???????? 
#define HOOKPOS_CObject_Remove      ???????? 
  
#define VTBL_CObject          ????????

Feel free to contribute to the above code, it would be really great if it will work.
