Cross: Thx, that helped me a lot! They don't really look perfect, but I guess after 2-3 hours of editing it might be O.K.
mkr8683: Thank you, that would be really nice. I didn't really want to request something like that, as I guessed that any modders have too much work and not enough time to make their own stuff.

I guess I'll send you a PM with the screenshots I have of these vehicles, if my conversion won't work out. Thx again.
