First of all, you'll have to change all of the datablock names so it doesn't overwrite the Jeep's stuff.
So whenever you see
datablock BLAHBLAHData(SomeName)
Change SomeName to a unique name.
Next. In the server.cs you're telling it to execute the file jeep_BrickExplosion.cs. But if you look in your folder, the file is called jeep_Explosion.cs, so the file you're telling it to execute doesn't exist.
But since you're only having 1 line of code in your server.cs, I suggest moving all of the code in jeep_Explosion.cs to the server.cs(because it's annoying when people only have 1 line of code in their server.cs).
You're also telling it to use the model block.dts, which doesn't exist. You're file is called brick.dts.
Also, when you rename the datablocks, you'll have to set some of the things in the datablocks to the appropriate names.
