American van magazines.What were they?

I remember back in the 1970s when I was a teenager looking through the newsagent in West Lakes Mall (Adelaide) at various van magazine.There was "Custom Van & Trucks" and Van Wheels and then there were a few American magazines.Vans that were chopped,sectioned and extended and so on.What were those magazines called?
If you have any could you scan the covers and post them here? I havent seen those magazines in years. Did anyone here collect them?

Thanks.
