Well after much head scratching and sleepless nights I figured out why the speedo was not working. Actually it was working but backwards! I never looked at it when backing up as I was looking in the mirrors. After messing around with it tonight I had my son in the cab and when I reversed he said dad its working, so I tried it again and sure enough it was working only when I was in reverse. I took the adapter off the transfer again(5th or sixth time)and noticed that on the label it says rotation "same". I took this to mean that when I turned the part that goes in the transfer clockwise the speedo cable end should go clockwise, it did not, it turned the opposite direction. I brought it to work to get a second opinion and my co-worker said try swapping the ends, as it turns out the speedo end and the end with the grease fitting are the same threads and the internal gear is center mounted, so I swapped ends and sure enough now the roation is the "same". Not only did it work but with the opposite orientation there is more clearance to mount it as the body of the adapter is taller on one side. I am not sure how it got reversed only perhaps a factory blunder as it looks like it never had been taken apart and it was cleaner than the area around it. Oh well another part of the puzzle solved.
