Hello, I have a problem and it is that I recently tried to add a truck to my server, but the problem is that this truck comes in parts, that is, they have to put certain parts in the mechanic so that they can be seen, but when trying to put them in the mechanic they do not even appear as an option to put, I already tried to put them as extras but they do not appear in those options either. If anyone knows what I can do I would appreciate it very much.
