Did you go to the right workshop, you need to be in the ETS2 section before you can search for ETS2 mods.

Thanks ... I think I somehow was in the wrong workshop but mansged to get a link from SCS to the same link you just gave so hopefully it works now ... How much time does it take to be able to buy it in the game then if ones just started ? Start driving the real thing Monday so was hoping to get in some practice

I have no idea, I don't play with that mod.
