Meta Files

So I made a really bad mistake, I was downloading new vehicles for lfspdfr, and when I picked the ones I liked and put them into open IV, I found one with things like vehicles.meta, handling.meta, carvariations.meta, and carcols.meta, and so I just looked up if and where to put them. Without looking thouroughly or researching more, I just dragged them into the meta file. Well, the game just started crashing. So I deleted the meta files (from the car pack) and then looked up what to do to fix it. I did the part where you go into update (not in mods) and drag them into mods and then the same place. It worked, I was able to launch the game, but my vehicles looked weird. So now I don't know what to do, I deleted my mods folder, I just really need help please. These are the pictures of the cars that are acting up that I know of (Some of them look alright/fine, I just don't know if there all broken or what), as well as the meta files I had dragged into my meta folder. Btw, the trackhawks lights don't work, the yellow parts on the ground as well as on the mirror are suppose to show the yellow light reflecting and as you can see, there are no yellow lights in the back. Also if you have seen the trackhawk pack or the newest one, the lights are very clean and sharp as the trackhawk, but mine are blurry and just regular white lights. PS, sorry it being so long, but I had both these cars before I had made the mistake and both of these problems never occurred until now.
