Custom vehicle configurations on server?

I would like to keep a vanilla server without mods and have some vehicle configurations I want to share on my server.
Is this possible? I have the .pc and .jpg files, but unsure if it’s even possible.
Or do I need the repack the config files as a mod?

You will need to make your custom config files a mod. People have done it before, I dont know exactly how to do it. Perhaps google can help.

Yeah. I made a mod and it kinda works (configs only shows up in the save & load list).
I made a thread on the BeamNG forum in the modding section.
