Not sure about ‘mod shops’ that need hashes. but for vehicle names use this:
Citizen.CreateThread(function()
AddTextEntry("vehicle spawn/model name", "display name you want")
end)
note that there’s no hashes in this, it’s just using the vehicle’s model name.
For hashes, use this instead:
Citizen.CreateThread(function()
AddTextEntryByHash(<hash>, "text")
end)
