Need help with .meta files

I am trying to add a brush truck as a addon for our fire department. The truck already had a handling.meta file in with vehicle however they left a txt file with what to add in the carcols,carvariations and vehicles.meta. I did as was instructed but i must have done something wrong cause FiveM crashes when i try getting in saying something with the vehicle.meta file error. Is there anyone very familiar with the .meta files that would be willing to assist me. Please join our TS @ vfr.teamspeak.network and speak to Dre(Commissioner) if you can and are able to assist. Thanks for any help!
