Hy guys, I don't know where I was or what I was paying attention to while this was originally happening but I seem to have missed the whole thing. I have always wanted an 860, the uniqueness of the design has always appealed to me. I would dearly love to see the build album. I believe that the 860 was the model that GMC chose to unveil there truck air suspension on. Bill Marlow I am exceeding jealous.
