change default vehicles

Hello, since I want to play a map with all vehicles changed how can I change the default vehicles into the modded one?

For example, in the first map I've changed first 3 vehicles with 3 that I've downloaded, but i can't change the other, is this possible?
Thanks

yes, go to spintires mod--> level editor --> classes tab then trucks and in there you can change the names of the trucks to the alphanumeric name of the mods you want

or you can just load them with spintires mod with the dev menu and delete the stock ones
