Those diffs are quite a bit different Joe. I did find a set of 1/8 scale diffs on a German site that are very close and they even had working planetaries but I think I would have to sell my house to afford them!
I took a couple days off from the 850(went and looked at the real trucks again yesterday) but I was back on it a little today. I built the ladders on the water tank and the engine side covers. I also mounted the fuel and water tanks to the rails.
Thanks for looking!
