@JerseyShoreModding From what I’ve managed to find out so far, it would probably be best to contact OS Farms. It looks like Smeby works with them. Unfortunately, I don’t think I can help you any further...

By the way, they also released this mod. https://www.kingmods.net/en/fs25/mods/79022/loftness-f1210
@JerseyShoreModding I’m not the author of this mod; the author is Smeby.
Just a piece of advice. Whenever you add something to an i3D file, always place it at the end of the existing shapes. I had a look at the i3D for this Zetor, and I'm actually surprised it works at all. For example, the beer you added inside the cab was inserted higher up in the hierarchy, which isn't the right way to do it. By doing that, you shifted the indices of everything below it. You also completely removed the placeholder for the front license plate, which is why it's showing up incorrectly. Its index now points to the drive belt instead.
