I recently downloaded this pack of police cars but the names go from police to police 9. Is it possible to install every single one of these? In default GTA there is only police up to police 4. Is there a way to modify the game so I can have more slots?

Could you perhaps link the pack for me?

 

I forgot where I downloaded the original one but here is a pack with 5 sheriffs, there is only 2 sheriff slots in the game and the names of the files go up to sheriff 5. Is there a way to implement more slots so I could use all 5?

In this case, I'm assuming Stobe lets you choose the two you would like in your game and rename them.

Else, if you want all of the vehicles as an addon, click on the DLC RPF Link.
