Create a public callback "SaveComponent" and don't forget to forward it (forward SaveComponent(vehicleid, componentid);) on top of your script.

public SaveComponent(vehicleid,componentid)
{
new playerid = GetDriverID(vehicleid);
if(GetPlayerState(playerid) == PLAYER_STATE_DRIVER) {
if (strcmp(VehicleInfo[vehicleid][owner],PlInfo[playerid][name],false) == 0) {
for(new s=0; s<20; s++) {
if(componentid == spoiler[s][0]) {
VehicleInfo[vehicleid][mod1] = componentid;
}
}
for(new s=0; s<3; s++) {
if(componentid == nitro[s][0]) {
VehicleInfo[vehicleid][mod2] = componentid;
}
}
for(new s=0; s<23; s++) {
if(componentid == fbumper[s][0]) {
VehicleInfo[vehicleid][mod3] = componentid;
}
}
for(new s=0; s<22; s++) {
if(componentid == rbumper[s][0]) {
VehicleInfo[vehicleid][mod4] = componentid;
}
}
for(new s=0; s<28; s++) {
if(componentid == exhaust[s][0]) {
VehicleInfo[vehicleid][mod5] = componentid;
}
}
for(new s=0; s<2; s++) {
if(componentid == bventr[s][0]) {
VehicleInfo[vehicleid][mod6] = componentid;
}
}
for(new s=0; s<2; s++) {
if(componentid == bventl[s][0]) {
VehicleInfo[vehicleid][mod7] = componentid;
}
}
for(new s=0; s<4; s++) {
if(componentid == bscoop[s][0]) {
VehicleInfo[vehicleid][mod8] = componentid;
}
}
for(new s=0; s<13; s++) {
if(componentid == rscoop[s][0]) {
VehicleInfo[vehicleid][mod9] = componentid;
}
}
for(new s=0; s<21; s++) {
if(componentid == lskirt[s][0]) {
VehicleInfo[vehicleid][mod10] = componentid;
}
}
for(new s=0; s<21; s++) {
if(componentid == rskirt[s][0]) {
VehicleInfo[vehicleid][mod11] = componentid;
}
}
for(new s=0; s<1; s++) {
if(componentid == hydraulics[s][0]) {
VehicleInfo[vehicleid][mod12] = componentid;
}
}
for(new s=0; s<1; s++) {
if(componentid == base[s][0]) {
VehicleInfo[vehicleid][mod13] = componentid;
}
}
for(new s=0; s<2; s++) {
if(componentid == rbbars[s][0]) {
VehicleInfo[vehicleid][mod14] = componentid;
}
}
for(new s=0; s<2; s++) {
if(componentid == fbbars[s][0]) {
VehicleInfo[vehicleid][mod15] = componentid;
}
}
for(new s=0; s<17; s++) {
if(componentid == wheels[s][0]) {
VehicleInfo[vehicleid][mod16] = componentid;
}
}
for(new s=0; s<2; s++) {
if(componentid == lights[s][0]) {
VehicleInfo[vehicleid][mod17] = componentid;
}
}
return 1;
}
}
return 0;
}

Also don't forget to tell your script when to SaveComponent:

public OnVehicleMod(vehicleid,componentid)
{
SaveComponent(vehicleid, componentid);
return 1;
}

If you want your vehicle to spawn with the saved mods:

public OnVehicleSpawn(vehicleid)
{
ModVehicle(vehicleid);
return 1;
}

Don't forget to add the function "ModVehicle".

stock ModVehicle(vehicleid)
{
new tuned2 = 0;
if(VehicleInfo[vehicleid][mod1] != 0) {
AddVehicleComponent(vehicleid,VehicleInfo[vehicleid][mod1]);
tuned2 = 1;
}
if(VehicleInfo[vehicleid][mod2] != 0) {
AddVehicleComponent(vehicleid,VehicleInfo[vehicleid][mod2]);
tuned2 = 1;
}
if(VehicleInfo[vehicleid][mod3] != 0) {
AddVehicleComponent(vehicleid,VehicleInfo[vehicleid][mod3]);
tuned2 = 1;
}
if(VehicleInfo[vehicleid][mod4] != 0) {
AddVehicleComponent(vehicleid,VehicleInfo[vehicleid][mod4]);
tuned2 = 1;
}
if(VehicleInfo[vehicleid][mod5] != 0) {
AddVehicleComponent(vehicleid,VehicleInfo[vehicleid][mod5]);
tuned2 = 1;
}
if(VehicleInfo[vehicleid][mod6] != 0) {
AddVehicleComponent(vehicleid,VehicleInfo[vehicleid][mod6]);
tuned2 = 1;
}
if(VehicleInfo[vehicleid][mod7] != 0) {
AddVehicleComponent(vehicleid,VehicleInfo[vehicleid][mod7]);
tuned2 = 1;
}
if(VehicleInfo[vehicleid][mod8] != 0) {
AddVehicleComponent(vehicleid,VehicleInfo[vehicleid][mod8]);
tuned2 = 1;
}
if(VehicleInfo[vehicleid][mod9] != 0) {
AddVehicleComponent(vehicleid,VehicleInfo[vehicleid][mod9]);
tuned2 = 1;
}
if(VehicleInfo[vehicleid][mod10] != 0) {
AddVehicleComponent(vehicleid,VehicleInfo[vehicleid][mod10]);
tuned2 = 1;
}
if(VehicleInfo[vehicleid][mod11] != 0) {
AddVehicleComponent(vehicleid,VehicleInfo[vehicleid][mod11]);
tuned2 = 1;
}
if(VehicleInfo[vehicleid][mod12] != 0) {
AddVehicleComponent(vehicleid,VehicleInfo[vehicleid][mod12]);
tuned2 = 1;
}
if(VehicleInfo[vehicleid][mod13] != 0) {
AddVehicleComponent(vehicleid,VehicleInfo[vehicleid][mod13]);
tuned2 = 1;
}
if(VehicleInfo[vehicleid][mod14] != 0) {
AddVehicleComponent(vehicleid,VehicleInfo[vehicleid][mod14]);
tuned2 = 1;
}
if(VehicleInfo[vehicleid][mod15] != 0) {
AddVehicleComponent(vehicleid,VehicleInfo[vehicleid][mod15]);
tuned2 = 1;
}
if(VehicleInfo[vehicleid][mod16] != 0) {
AddVehicleComponent(vehicleid,VehicleInfo[vehicleid][mod16]);
tuned2 = 1;
}
if(VehicleInfo[vehicleid][mod17] != 0) {
AddVehicleComponent(vehicleid,VehicleInfo[vehicleid][mod17]);
tuned2 = 1;
}
if(tuned2 == 1) {
tuned++;
}
}

All you need now is the GetDriverID(vehicleid) function. Here it is:

stock GetDriverID(vehicleid)
{
for(new i=0; i<MAX_PLAYERS; i++)
{
if(GetPlayerVehicleID(i) == vehicleid && GetPlayerState(i) == 2) return i;
}
return -1;
