Support the original creator "GTAWiseGuy"

I did not create the model of the vehicle. All I did is create an add-on package for the vehicle. If the original creator is unhappy with this conversion, then I will take down the mod.

How to install:

1.Put "sentinelc" folder in mods\update\x64\dlcpacks
2.Add this line <Item>dlcpacks:\sentinelc\</Item> to the dlclist.xml (mods\update\update.rpf\common\data) 
3. Use "sentinelc" to spawn the vehicle in-game
