Thank you very much. The 73-87 are not so uncommon as you might think but I have the only long stepper here as far as I know. evrey time I drive it it gets a lot of attention, especially since I have lowered it.
I bought this truck several years ago from an American business man who has been living here with his German wife. He went in financial trouble and so it was my turn. I felt in love with it at first view and now step by step I try to turn it into the way I like it.
