gta sa > rhini & rancher to a new id

there are plenty of tutorials and so on. on the topic of adding a transport to a new id , but here's the problem with the transport which has a tower in the likeness of the tank and Svaty .
Does anyone know how to add them to a new id.? (roughly speaking, that in game there was 2 tanks but with different id ). The problem is that I don't know how to apply the functionality of the tank to transport the new id , namely the rotation Besni , podem guns regarding the tower ,well, and shooting. (with regards to shooting it has the script canon.cs who was forced to shoot though and the bike, but the sight hasn't moved, as there is no turret)
