When your game is updated you will need to reinstall them.
And use Patchday 24

You can play LCPDFR with the Steam version of Grand Theft Auto IV. Just follow the Instruction and Install the LCPDFR and this https://www.lcpdfr.com/downloads/gta4mods/g17media/26726-compatibility-patch-for-gta-iv-complete-edition/ Compatibility Patch.

will give it a run
 
Holy shit it worked!!!!! Thank you brooo!!
wait @Mud im crashing again bro 😞
 

yes just an empty .txt

Just to add on here, it is suggested to use 22 since it is a universal replace location. That means that even if the vehicles files aren't already in there, it should still replace the vehicle.

Thank you very much sir much appreciated! 

These will make Supported ELS Models All blue through VCF and Texture Edits.

the FIB vehicles are FBI for the Charger like vehicle and FBI2 for the Tahoe like vehicle. For the blue lights, are you using ELS or Non-ELS?

I would suggest 19-22 since 23 doesn't seem to work for much at all, just make sure it isn't being overwritten by another patchday. Make sure you change the handling in your vehicles.meta so you don't have the old handling if you don't want it.

If you are referring to the north yankton cars from the beginning of the game policeold1 is the suv and policeold2 is the sedan

Glad I could be of help
