If the replacer vehicle doesn't spawns but the vanilla one does, the problem is that the game finds the vanilla vehicle as the most recent version. That can be caused because of the following:

1.- The EMF folder is not being read by the game when you start it. Make 100% sure that you've installed it correctly, following every step, without mistakes of any kind.
2.- The LSSD Charger vehicle that you've mentioned does not work or the files of the vehicle installed are corrupt, which makes the game unable to load it and instead spawns the most recent "police2" files found.
3.- If it still doesn't work and you've verified that's not a mistake with its installation, you still have the chance to try another installation method, similar to EMF. If you want to try this method, I'd suggest you to do a test with the tutorial available first. If you got the tutorial example working, then you should be able to create your own Add-Ons, because you'd have made one!

@GTAV-Noob-Modder117 You can reach 3.5gb (or a higher size, which I don't recommend) for each dlc.rpf file.

@katysz the answer is there.. yes scaling a block is a good idea. . but you need to avoid using .yft model and check if a .ydr file if it has only 1 geometry meshed. ( extract to open formats look for a .mesh file open it with notepad++ . .)

get another block if it is not scalable.

Install Microsoft .NET Framework 4.5.2 (or higher, so skip this step on Windows 10)

AND Microsoft Visual C++ Redistributable Package for Visual Studio 2013 (x64).
AND Microsoft Visual C++ Redistributable Package for Visual Studio 2015 (x64).

Download and install the latest Script Hook V. Alsways re-do this step after a R* update is pushed.
Download and install Community Script Hook V .NET and copy the ScriptHookVDotNet.asi and ScriptHookVDotNet2.dll in the main game folder

@Walter that tool script . train utility menü

Train.Models = freight, streak1, ca23,
; models of the freight train loco (multiple models separated by comma)

I Solved the problem turned out to be Visual C++ 2010 also 2015.

@Yarm1995 that looks awesome. I guess it's ironing out textures, bug testing and then officials release!

@ReNNie
I'm using those but yeah I'd like to restore the shaders.

As Reacon so friendly pointed out it has to be UV mapped in zmod3 which is the software tool used to convert vehicles from other PC games into GTA V file format yft and ytd.

UV mapping means the bodyshell of the vehicle is layed out to a template so you can apply a Paintjob to it
Vehicles that have this are tagged on the 5mods page by having [Template] in the title
