Thanks for the reply's i have a couple of things to check when I pick up the new truck in a couple of days, will get back to forum with a bit more information. Pretty sure the truck is a 4 speed but i do not thing it has the Timmens 2 speed diff, Where would the switch be located for selecting the hi/lo ration tried googling this without success. I do have a picture of the dash but nothing much is obvious at this time. i have included a couple of pictures basically I have not seen the vehicle in the flesh so to speak as of yet.
